E825C devices shall support the new signing type of RSA 3K for new DDP
section (SEGMENT_SIGN_TYPE_RSA3K_E825 (5) - already in the code).
The driver is responsible to verify the presence of correct signing type.
Add 3k signinig support for E825C devices based on mac_type:
ICE_MAC_GENERIC_3K_E825;

E800 series devices have a couple of quirks:
1. Sideband control queues are not supported
2. The registers that the driver needs to program for the "Precision
Time Protocol (PTP)" feature are different for E800 series devices
compared to other devices supported by this driver.
Both these require conditional logic based on the underlying device we
are dealing with.
The function ice_is_sbq_supported added by commit 8f5ee3c477a8
("ice: add support for sideband messages") addresses (1).
The same function can be used to address (2) as well
but this just looks weird readability wise in cases that have nothing
to do with sideband control queues:
if (ice_is_sbq_supported(hw))
/* program register A */
else
/* program register B */
For these cases, the function ice_is_generic_mac introduced by this
patch communicates the idea/intention better. Also rework
ice_is_sbq_supported to use this new function.
As side-band queue is supported for E825C devices, it's mac_type is
considered as generic mac_type.

Introduce new Intel Ethernet E825C family devices.
Add new PCI device IDs which are going to be supported by the
driver:
- 579C: Intel(R) Ethernet Connection E825-C for backplane
- 579D: Intel(R) Ethernet Connection E825-C for QSFP
- 579E: Intel(R) Ethernet Connection E825-C for SFP
- 579F: Intel(R) Ethernet Connection E825-C for SGMII
Add helper function ice_is_e825c() to verify if the running device
belongs to E825C family.

TSO and TBS cannot co-exist. TBS requires special descriptor to be

TSO and TBS can help in allocating those resources at bootup.
TX queues with TBS can support etf qdisc hw offload.
This is similar to the patch raised by NXP

There is a crash when adding one of the lan966x interfaces under a lag
interface. The issue can be reproduced like this:
ip link add name bond0 type bond miimon 100 mode balance-xor
ip link set dev eth0 master bond0
The reason is because when adding a interface under the lag it would go
through all the ports and try to figure out which other ports are under
that lag interface. And the issue is that lan966x can have ports that are
NULL pointer as they are not probed. So then iterating over these ports
it would just crash as they are NULL pointers.
The fix consists in actually checking for NULL pointers before accessing
something from the ports. Like we do in other places.

While individual filter structures are allocated as needed, there is an
array to keep track of the software filter IDs that we allocate ahead
of time. Rather than relying on a fixed maximum filter count to
allocate this array, get the maximum from the firmware when available.
Move these filter related maximum counts queried from the firmware to the
bnxt_hw_resc struct. If the firmware is not providing these maximum
counts, fall back to the hard-coded constant.

TOE has hardware support for calculating IP header and TCP/UDP/ICMP
checksum for both IPv4 and IPv6.
Add Tx checksum offload supported by TOE for IPv4 and TCP/UDP.
For Tx, the result of checksum calculation is set to the checksum field of
each IPv4 Header/TCP/UDP/ICMP of ethernet frames. For the unsupported
frames, those fields are not changed. If a transmission frame is an UDPv4
frame and its checksum value in the UDP header field is 0x0000, TOE does
not calculate checksum for UDP part of this frame as it is optional
function as per standards.
We can test this functionality by the below commands
ethtool -K eth0 tx on --> to turn on Tx checksum offload

If a frame does not have checksum error, 0x0000 is attached as checksum

I didn't manage to reproduce it. Though the issue seems to be obvious.
There is a chance that the mlx5_dpll_remove() calls
cancel_delayed_work() when the work runs and manages to re-arm itself.
In that case, after delay timer triggers next attempt to queue it,
it works with freed memory.
Fix this by using cancel_delayed_work_sync() instead which makes sure
that work is done when it returns.
