Version : 1.26.4.0
Date : 12/02/2021

Fixes
-----

BASE:
- Fixed error on setting 25G speed on 100G copper with multiple FEC set in
firmware commands.
- Handle link of unknown optics modules by enabling module tx unconditionally.
- Fixed link not coming up for 25G CRS phys. Firmware incorrectly tried to
bring up the link in RS-FEC but as per IEEE spec, it must be BASER FEC.
- Fixed an issue where firmware doesn't automatically retry next FEC if driver
asks to bring up the link using RS-FEC and link doesn't come up.

mlx5en: Implement support for internal queues, IQ.

Internal send queues are regular sendqueues which are reserved for WQE commands
towards the hardware and firmware. These queues typically carry resync
information for ongoing TLS RX connections and when changing schedule queues
for rate limited connections.

The internal queue, IQ, code is more or less a stripped down copy
of the existing SQ managing code with exception of:

1) An optional single segment memory buffer which can be read or
written as a whole by the hardware, may be provided.
2) An optional completion callback for all transmit operations, may
be provided.
3) Does not support mbufs.

LinuxKPI: import beginning of a new version of netdevice.h

Import a netdevice update complementing the last remaining bits of
the old ifnet derived implementation. Along add a (for now) task
based NAPI implementation.

This is the minimal set of chnages which are needed for the initial
support of wireless drivers. The NAPI implementation has an option to
still switch to "direct dispatch" as it had been used by these drivers
before not relying on a deferred context along with some printf tracing.
This has been helpful in the last weeks for debugging and will be
cleaned once we have had broader testing and are sure this is fine as-is.
Should we need a more time-sensitive or load-sensitive response
in the future we can always switch to something more sophisticated.

LinuxKPI: add a work-in-progress skbuff implementation

This is a work-in-progress implementation of sk_buff compat code
used for wireless drivers only currently.
Bring in this version of the code as it has proven to be good enough
to have packets going for a few months.

The current implementation has several drawbacks including the need
for us to copy data between sk_buffs and mbufs.
Do not rely on the internals of this implementation. They are highly
likely to change as we will improve the integration to FreeBSD mbufs.

netinet: Deduplicate most in_cksum() implementations

in_cksum() and related routines are implemented separately for each
platform, but only i386 and arm have optimized versions. Other
platforms' copies of in_cksum.c are identical except for style
differences and support for big-endian CPUs.

Deduplicate the implementations for the rest of the platforms. This
will make it easier to implement in_cksum() for unmapped mbufs. On arm
and i386, define HAVE_MD_IN_CKSUM to mean that the MI implementation is
not to be compiled.

No functional change intended.

Add the KASAN runtime

KASAN enables the use of LLVM's AddressSanitizer in the kernel. This
feature makes use of compiler instrumentation to validate memory
accesses in the kernel and detect several types of bugs, including
use-after-frees and out-of-bounds accesses. It is particularly
effective when combined with test suites or syzkaller. KASAN has high
CPU and memory usage overhead and so is not suited for production
environments.

The runtime and pmap maintain a shadow of the kernel map to store
information about the validity of memory mapped at a given kernel
address.

The runtime implements a number of functions defined by the compiler
ABI. These are prefixed by __asan. The compiler emits calls to
__asan_load*() and __asan_store*() around memory accesses, and the
runtime consults the shadow map to determine whether a given access is
valid.

kasan_mark() is called by various kernel allocators to update state in
the shadow map. Updates to those allocators will come in subsequent
commits.

The runtime also defines various interceptors. Some low-level routines
are implemented in assembly and are thus not amenable to compiler
instrumentation. To handle this, the runtime implements these routines
on behalf of the rest of the kernel. The sanitizer implementation
validates memory accesses manually before handing off to the real
implementation.

The sanitizer in a KASAN-configured kernel can be disabled by setting
the loader tunable debug.kasan.disable=1.

Fixes
-----

BASE:
- Fixed Back to back T6 100G-CR4 link coming up with NO FEC sometimes.
- [T5] Try to bring up link in 1G speed if link doesn't come up on 10G.
- Fixed a bug to not allow BaseR fec in 100G speed.
- Fixed linkup issues on BT adapter in 1G and 100M speed.
- Fixed an issue to allow driver to send VI_ENABLE multiple times (once
with rx disable and then later rx enable).
- Fixed rate limiting not working on class number 16 to 30.
- Fixed backward compatibility issue in port type interpretation with vpd
version 0x80.

ETH:
- Fixed a case when firmware failed to deliver NIC WR completion to host.
- No rate limit support for WR ETH_TX_PKTS2 due to performance reasons.

OFLD

is more than the window size.
- Added fw_filter_vnic_mode to firmware API file (t4fw_interface.h)
- Use correct rx channel in coprocessor crypto completion (CPL_FW6_PLD). This
was causing out of order completion to host.

FOiSCSI

Enhancements
------------

ETH:
- Rate limiting support added for encapsulated (vxlan, nvgre, geneve) NIC TCP
