put the device to D3cold, and ipc_pcie_suspend_s2idle() is to keep the

The blamed commit changed the vlan used by the host ports to be 4095
instead of 0.
Because of this change the following issues are seen:
- when the port is probed first it was adding an entry in the MAC table
with the wrong vlan (port->pvid which is default 0) and not HOST_PVID
- when the port is removed from a bridge, it was using the wrong vlan to
add entries in the MAC table. It was using the old PVID and not the
HOST_PVID
This patch fixes this two issues by using the HOST_PVID instead of
port->pvid.

If NETIF_F_GRO_HW is disabled, the existing driver code uses kmalloc'ed
data for RX buffers. This causes inefficient SW GRO performance
because the GRO data is merged using the less efficient frag_list.
Use netdev_alloc_frag() and friends instead so that GRO data can be
merged into skb_shinfo(skb)->frags for better performance.

CQE coalescing mode is the same as the timer reset coalescing mode
on Broadcom devices. Currently this mode is always enabled if it
is supported by the device. Restructure the code slightly to support
dynamically changing this mode.
Add a flags field to struct bnxt_coal. Initially, the CQE flag will
be set for the RX and TX side if the device supports it. We need to
move bnxt_init_dflt_coal() to set up default coalescing until the

There are two ICOSQs per channel: one is needed for RX, and the other
for async operations (XSK TX, kTLS offload). Currently, the recovery
flow for both is the same, and async ICOSQ is mistakenly treated like
the regular ICOSQ.
This patch prevents running the regular ICOSQ recovery on async ICOSQ.
The purpose of async ICOSQ is to handle XSK wakeup requests and post
kTLS offload RX parameters, it has nothing to do with RQ and XSKRQ UMRs,
so the regular recovery sequence is not applicable here.

Both regular RQ and XSKRQ use the same ICOSQ for UMRs. When doing
recovery for the ICOSQ, don't forget to deactivate XSKRQ.
XSK can be opened and closed while channels are active, so a new mutex
prevents the ICOSQ recovery from running at the same time. The ICOSQ
recovery deactivates and reactivates XSKRQ, so any parallel change in
XSK state would break consistency. As the regular RQ is running, it's
not enough to just flush the recovery work, because it can be
rescheduled.

====================
mlx5-updates-2021-12-21
1) From Shay Drory: Devlink user knobs to control device's EQ size
This series provides knobs which will enable users to
minimize memory consumption of mlx5 Functions (PF/VF/SF).
mlx5 exposes two new generic devlink params for EQ size
configuration and uses devlink generic param max_macs.

2) From Tariq and Lama, allocate software channel objects and statistics
of a mlx5 netdevice private data dynamically upon first demand to save on
memory.

Commit d068ca2ae2 ("codel: split into multiple files") moved all
Qdisc-related code to codel_qdisc.h, move the include of pkt_sched.h
as well.
This is similar to the previous commit, although we don't care as
much about incremental builds after pkt_sched.h was touched itself
it is included by net/sch_generic.h which is modified ~20 times
a year.
This decreases the incremental build size after touching pkt_sched.h
from 1592 to 617 objects.
Fix unmasked missing includes in WiFi drivers.

Since sock.h is modified relatively often (60 times in the last
12 months) it seems worthwhile to decrease the incremental build
work.
CoDel's header includes net/inet_ecn.h which in turn includes net/sock.h.
codel.h is itself included by mac80211 which is included by much of
the WiFi stack and drivers. Removing the net/inet_ecn.h include from
CoDel breaks the dependecy between WiFi and sock.h.
Commit d068ca2ae2 ("codel: split into multiple files") moved all
the code which actually needs ECN helpers out to net/codel_impl.h,
the include can be moved there as well.
This decreases the incremental build size after touching sock.h
from 4999 objects to 4051 objects.
Fix unmasked missing includes in WiFi drivers.

The variable bytes is being used to summate slot lengths,
however the value is never used afterwards. The summation
is redundant so remove variable bytes.

Fix an odd indent where some code was left indented, and causes smatch
to warn:
ice_log_pkg_init() warn: inconsistent indenting
While here, for consistency, add a break after the default case.

If asix_read_cmd() returns 0 on 30th interation, 0 will be returned from
asix_check_host_enable(), which is logically wrong. Fix it by returning
-ETIMEDOUT explicitly if we have exceeded 30 iterations
Also, replaced 30 with #define as suggested by Andrew

====================
100GbE Intel Wired LAN Driver Updates 2021-12-21
This series contains updates to ice driver only.
Karol modifies the reset flow to correct issues with PTP reset.
Jake extends PTP support for E822 based devices. This includes a few
cleanup patches, that fix some minor issues. In addition, there are some
slight refactors to ease the addition of E822 support, followed by adding
the new hardware implementation ice_ptp_hw.c.
There are a few major differences with E822 support compared to E810
support:
*) The E822 device has a Clock Generation Unit which must be initialized in
order to generate proper clock frequencies on the output that drives the PTP
hardware clock registers
*) The E822 PHY is a bit different and requires a more complex
initialization procedure which must be rerun any time the link configuration
changes.
*) The E822 devices support enhanced timestamp calibration by making use of
a process called Vernier offset measurement. This allows the hardware to
measure phase offset related to the PHY clocks for Serdes and FEC, reducing
the inaccuracy of the timestamp relative to the actual packet transmission
and receipt. Making use of this requires data gathered from the first
transmitted and received packets, and waiting for the PHY to complete the
calibration measurements. This is done as part of a new kthread, ov_work.
Note that to avoid delay in enabling timestamps, we start the PHY in
'bypass' mode which allows timestamps to be captured without the Vernier
calibration measurement. Once the first packets have been sent and received,
we then complete the calibration setup and exit bypass mode and begin using
the more precise timestamps. According to the datasheet, timestamps without
calibration data can be incorrect relative to actual receipt or transmission
by up to 1 clock cycle (~1.25 nanoseconds), while calibrated timestamps
should be correct to within 1/8th of a clock cycle (~0.15 nanoseconds).
*) E822 devices support crosstimestamping via PCIe PTM, which we enable when
available on the platform.
There is a fair amount of logic required to perform PHY and CGU
initialization, which is the vast majority of the new code, but it is fairly
self contained within ice_ptp_hw.c, with the exception of monitoring for
offset validity being handled by a kthread.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: support crosstimestamping on E822 devices if supported
ice: exit bypass mode once hardware finishes timestamp calibration
ice: ensure the hardware Clock Generation Unit is configured
ice: implement basic E822 PTP support
ice: convert clk_freq capability into time_ref
ice: introduce ice_ptp_init_phc function
ice: use 'int err' instead of 'int status' in ice_ptp_hw.c
ice: PTP: move setting of tstamp_config
ice: introduce ice_base_incval function
ice: Fix E810 PTP reset flow

Because of the possible failure of the kcalloc, it should be better to
set rx_queue->page_ptr_mask to 0 when it happens in order to maintain
the consistency.
