Each multicast route that is forwarding packets (as opposed to trapping
them) points to a list of egress router interfaces (RIFs) through which
packets are replicated.
A route's action can transition from trap to forward when a RIF is
created for one of the route's egress virtual interfaces (eVIF). When
this happens, the route's action is first updated and only later the
list of egress RIFs is committed to the device.
This results in the route pointing to an invalid list. In case the list
pointer is out of range (due to uninitialized memory), the device will
complain:
mlxsw_spectrum2 0000:06:00.0: EMAD reg access failed (tid=5733bf490000905c,reg_id=300f(pefa),type=write,status=7(bad parameter))
Fix this by first committing the list of egress RIFs to the device and
only later update the route's action.
Note that a fix is not needed in the reverse function (i.e.,
mlxsw_sp_mr_route_evif_unresolve()), as there the route's action is
first updated and only later the RIF is removed from the list.

Currently vport number to vport and its representor are mapped using an
array and an index.
Vport numbers of different types of functions are not contiguous. Adding
new such discontiguous range using index and number mapping is increasingly
complex and hard to maintain.
Hence, maintain an xarray of vport and rep whose lookup is done based on
the vport number.
Each VF and SF entry is marked with a xarray mark to identify the function
type. Additionally PF and VF needs special handling for legacy inline
mode. They are additionally marked as host function using additional
HOST_FN mark.

Total vports are already stored during eswitch initialization. Instead
of calculating everytime, read directly from eswitch.
Additionally, host PF's SF vport information is available using
QUERY_HCA_CAP command. It is not available through HCA_CAP of the
eswitch manager PF.
Hence, this patch prepares the return total eswitch vport count from the
existing eswitch struct.
This further helps to keep eswitch port counting macros and logic within

Handling comm_channel_event in mlx4_master_comm_channel uses a double
loop to determine which slaves have requested work. The search is
always started at lowest slave. This leads to unfairness; lower VFs
tends to be prioritized over higher VFs.
The patch uses find_next_bit to determine which slaves to handle.
Fairness is implemented by always starting at the next to the last

mlxsw used to hold an array of qdiscs indexed by the TC number. In the
previous patch, it was changed to allocate child qdiscs dynamically, and
they are now indexed by band number. Follow suit with the array of future

Instead of keeping qdiscs in globally-preallocated arrays, introduce a
per-qdisc-kind value num_classes, and then allocate the necessary child
qdiscs (if any) based on that value. Since now dynamic allocation is
involved, mlxsw_sp_qdisc_replace() gets messy enough that it is worth it to
split it to two cases: a new qdisc allocation and a change of existing
qdisc. (Note that the change also includes what TC formally calls replace,
if the qdisc kind is the same.)

The FIFO handler currently guards accesses to the future FIFO tracking by
asserting RTNL. In the future, the changes to the qdisc state will be more
thorough, so other qdiscs will need this guarding is as well. In order
to not further the RTNL infestation, instead convert to a custom lock that
will guard accesses to the qdisc state.

mlxsw currently allows a two-level structure of qdiscs: the root and
possibly a number of children. In order to support offloading more general
qdisc trees, introduce to struct mlxsw_sp_qdisc a pointer to child qdiscs.
Refer to the child qdiscs through this pointer, instead of going through
the tclass_qdiscs in qdisc_state. Additionally introduce a field
num_classes, which holds number of given qdisc's children.
Also introduce a generic function for walking qdisc trees. Rewrite
mlxsw_sp_qdisc_find() and _find_by_handle() to use the generic walker.
For now, keep the qdisc_state.tclass_qdisc, and just point root_qdiscs's
children to this array. Following patches will make the allocation dynamic.

When a qdisc is removed, it is necessary to update the backlog value at its
parent--unless the qdisc is at root position. RED, TBF and FIFO all do
that, each separately. Since all of them need to do this, just promote the
operation directly to mlxsw_sp_qdisc_destroy(), instead of deferring it to
individual destructors. Since FIFO dtor thus becomes trivial, remove it.
Add struct mlxsw_sp_qdisc.parent to point at the parent qdisc. This will be
handy later as deeper structures are offloaded. Use the parent qdisc to
find the chain of parents whose backlog value needs to be updated.

The purpose of this function is to filter out events that are related to
qdiscs that are not offloaded, or are not offloaded anymore. But the
function is unnecessarily thorough:
- mlxsw_sp_qdisc pointer is never NULL in the context where it is called
- Two qdiscs with the same handle will never have different types. Even
when replacing one qdisc with another in the same class, Linux will not
permit handle reuse unless the qdisc type also matches.
Simplify the function by omitting these two unnecessary conditions.

Currently when GID is deleted, it zero out all the fields of the RoCE
address in the SET_ROCE_ADDRESS command for a specified index.
roce_version = 0 means RoCEv1 in the SET_ROCE_ADDRESS command.
This assumes that device has RoCEv1 always enabled which is not always
correct. For example Subfunction does not support RoCEv1.
Due to this assumption a previously added RoCEv2 GID is always deleted as
RoCEv1 GID. This results in a below syndrome:
mlx5_core.sf mlx5_core.sf.4: mlx5_cmd_check:777:(pid 4256): SET_ROCE_ADDRESS(0x761) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x12822d)
Hence set the right RoCE version during GID deletion provided by the core.

When using SW steering, rule insertion rate depends on the RDMA RC QP
performance used for writing to the ICM. During stress this QP is competing
on the HW resources with all the other QPs that are used to send data.
To protect SW steering QP's performance in such cases, we set this QP to
use isolated VL. The VL number is reserved by FW and is not exposed to the
driver.
Support for this QP on isolated VL exists only when both force-loopback and
isolate_vl_tc capabilities are set.

As explained in bugfix commit 6ab4c3117a ("net: bridge: don't notify
switchdev for local FDB addresses") as well as in this discussion:
https://lore.kernel.org/netdev/20210117193009.io3nungdwuzmo5f7@skbuf/
the switchdev notifiers for FDB entries managed to have a zero-day bug,
which was that drivers would not know what to do with local FDB entries,
because they were not told that they are local. The bug fix was to
simply not notify them of those addresses.
Let us now add the 'is_local' bit to bridge FDB entries, and make all
drivers ignore these entries by their own choice.

In case the interface was set up but cannot establish the link, ethtool
will print more information to help the user troubleshoot the state.
For example, no link due to missing cable:

...
Link detected: no (No cable)
Beside the general extended state, drivers can pass additional
information about the link state using the sub-state field. For example:
$ ethtool eth1
...
Link detected: no (Autoneg, No partner detected)
The extended state is available only for specific cases, in other cases
ethtool with print only "Link detected: no" as before

mlx5e_safe_switch_channels accepts new_chs as a parameter and opens new
channels in place, then copying them to priv->channels. It requires all
the callers to allocate space for this temporary storage of the new
channels.
This commit cleans up the API by replacing new_chs with new_params, a
meaningful subset of new_chs to be filled by the caller. The temporary
space for the new channels is allocated inside mlx5e_safe_switch_params
(a new name for mlx5e_safe_switch_channels). An extra copy of params is
made, but since it's control flow, it's not critical.
