When we suspend and resume, we need to clear and re-enable the interrupt
scheme. This was previously not done while holding the RTNL lock, which
could be problematic, because we are actually destroying and re-creating

Hold the RTNL lock for the entire sequence of preparing for reset, and
when resuming. This additionally protects the flags related to interrupt
scheme under RTNL lock so that their modification is properly threaded.

Link events are posted to a PF's admin receive queue (ARQ). This patch
adds the ability to detect and process link events.
This patch also adds the ability to process resets.
The driver can process the following resets:
1) EMP Reset (EMPR)
2) Global Reset (GLOBR)
3) Core Reset (CORER)
4) Physical Function Reset (PFR)
EMPR is the largest level of reset that the driver can handle. An EMPR
resets the manageability block and also the data path, including PHY and
link for all the PFs. The affected PFs are notified of this event through
a miscellaneous interrupt.
GLOBR is a subset of EMPR. It does everything EMPR does except that it
doesn't reset the manageability block.
CORER is a subset of GLOBR. It does everything GLOBR does but doesn't
reset PHY and link.
PFR is a subset of CORER and affects only the given physical function.
In other words, PFR can be thought of as a CORER for a single PF. Since
only the issuing PF is affected, a PFR doesn't result in the miscellaneous
interrupt being triggered.
All the resets have the following in common:
1) Tx/Rx is halted and all queues are stopped.
2) All the VSIs and filters programmed for the PF are lost and have to be
reprogrammed.
3) Control queue interfaces are reset and have to be reprogrammed.
In the rebuild flow, control queues are reinitialized, VSIs are reallocated
and filters are restored.

This patch also implements ice_napi_poll, which is invoked when there's an
interrupt on the VSI's queues. The interrupt can be due to either a
completed Tx or an Rx event. In case of a completed Tx/Rx event, resources
are reclaimed. Additionally, in case of an Rx event, the skb is fetched

3) Add Rx queues by programming Rx queue context (implemented in

A VSI needs traffic directed towards it. This is done by programming
filter rules on the switch (embedded vSwitch) element in the hardware,
which connects the VSI to the ingress/egress port.
This patch introduces data structures and functions necessary to add
remove or update switch rules on the switch element. This is a pretty low
level function that is generic enough to add a whole range of filters.
This patch also introduces two top level functions ice_add_mac and
ice_remove mac which through a series of intermediate helper functions
eventually call ice_aq_sw_rules to add/delete simple MAC based filters.
It's worth noting that one invocation of ice_add_mac/ice_remove_mac
is capable of adding/deleting multiple MAC filters.
Also worth noting is the fact that the driver maintains a list of currently
active filters, so every filter addition/removal causes an update to this
list. This is done for a couple of reasons:
1) If two VSIs try to add the same filters, we need to detect it and do
things a little differently (i.e. use VSI lists, described below) as
the same filter can't be added more than once.
2) In the event of a hardware reset we can simply walk through this list
and restore the filters.
VSI Lists:
In a multi-VSI situation, it's possible that multiple VSIs want to add the
same filter rule. For example, two VSIs that want to receive broadcast
traffic would both add a filter for destination MAC ff:ff:ff:ff:ff:ff.
This can become cumbersome to maintain and so this is handled using a
VSI list.
A VSI list is resource that can be allocated in the hardware using the
ice_aq_alloc_free_res admin queue command. Simply put, a VSI list can
be thought of as a subscription list containing a set of VSIs to which
the packet should be forwarded, should the filter match.
For example, if VSI-0 has already added a broadcast filter, and VSI-1
wants to do the same thing, the filter creation flow will detect this,
allocate a VSI list and update the switch rule so that broadcast traffic
will now be forwarded to the VSI list which contains VSI-0 and VSI-1.

This patch introduces data structures and functions to alloc/free
VSIs. The driver represents a VSI using the ice_vsi structure.
Some noteworthy points about VSI allocation:
1) A VSI is allocated in the firmware using the "add VSI" admin queue
command (implemented as ice_aq_add_vsi). The firmware returns an
identifier for the allocated VSI. The VSI context is used to program
certain aspects (loopback, queue map, etc.) of the VSI's configuration.
2) A VSI is deleted using the "free VSI" admin queue command (implemented
as ice_aq_free_vsi).
3) The driver represents a VSI using struct ice_vsi. This is allocated
and initialized as part of the ice_vsi_alloc flow, and deallocated
as part of the ice_vsi_delete flow.
4) Once the VSI is created, a netdev is allocated and associated with it.
The VSI's ring and vector related data structures are also allocated
and initialized.
5) A VSI's queues can either be contiguous or scattered. To do this, the
driver maintains a bitmap (vsi->avail_txqs) which is kept in sync with
the firmware's VSI queue allocation imap. If the VSI can't get a
contiguous queue allocation, it will fallback to scatter. This is
implemented in ice_vsi_get_qs which is called as part of the VSI setup
flow. In the release flow, the VSI's queues are released and the bitmap
is updated to reflect this by ice_vsi_put_qs.

This patch adds to the initialization flow by getting switch
configuration, scheduler configuration and device capabilities.
Switch configuration:
On boot, an L2 switch element is created in the firmware per physical
function. Each physical function is also mapped to a port, to which its
switch element is connected. In other words, this switch can be visualized
as an embedded vSwitch that can connect a physical function's virtual
station interfaces (VSIs) to the egress/ingress port. Egress/ingress
filters will be eventually created and applied on this switch element.
As part of the initialization flow, the driver gets configuration data
from this switch element and stores it.
Scheduler configuration:
The Tx scheduler is a subsystem responsible for setting and enforcing QoS.
As part of the initialization flow, the driver queries and stores the
default scheduler configuration for the given physical function.
Device capabilities:
As part of initialization, the driver has to determine what the device is
capable of (ex. max queues, VSIs, etc). This information is obtained from
the firmware and stored by the driver.

Also, based on the number of queues available, the number of TX queues
may be reduced when an XDP program is loaded in order to accommodate the

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.

add a new parameter 'mode'. It forgot to document the parameter in the
doxygen function header comment. Add the parameter to the function
description now.

During suspend client MSIx vectors are freed while they are still
in use causing a crash on entering S3.
Fix this calling client close before freeing up its MSIx vectors.
Also update the client MSIx vectors on resume before client
open is called.
Fixes commit b980c0634f ("i40e: shutdown all IRQs and disable MSI-X
when suspended")

Setting link settings on backplane devices shouldn't be allowed.
This patch adds one more device id to the list which we check
that against.

The i40e_set_link_ksettings and i40e_get_link_ksettings use different
codepaths to check available and supported advertisement modes. This
creates scenarios where it's possible to set a mode that's not allowed,
resulting in a link down.
Fix setting advertisement in i40e_set_link_ksettings by calling
i40e_get_link_ksettings to check what modes are allowed.

While doing some code review I noticed that we can get into a state where
we exit with the "IN_CRITICAL_TASK" bit set while notifying the PF of
flower filters. This patch is meant to address that plus tweak the ordering
of the while loop waiting on it slightly so that we don't wait an extra
period after we have failed for the last time.

When we re-enable ATR we need to restore the input set for TCPv4
filters, in order for ATR to function correctly. We already do this for
the normal case of re-enabling ATR when disabling ntuple support.
However, when re-enabling ATR after the last TCPv4 filter is removed (but
when ntuple support is still active), we did not restore the TCPv4
filter input set.
This can cause problems if the TCPv4 filters from FDir had changed the
input set, as ATR will no longer behave as expected.
When clearing the ATR auto-disable flag, make sure we restore the TCPv4
input set to avoid this.

This patch overwrites number of ports for X722 devices with support
for OCP PHY mezzanine.
The old method with checking if port is disabled in the PRTGEN_CNF
register cannot be used in this case. When the OCP is removed, ports
were seen as disabled, which resulted in wrong calculation of partition
id, that caused WoL to be disabled on certain ports.

A future patch needs to expand on the logic for re-enabling ATR. Doing
so would cause some code to break the 80-character line limit.
To reduce the level of indentation, factor out helper functions for
re-enabling ATR and SB rules.
