[SRU Justification]

[Impact]
iwlwifi firmware crash under iperf stress tests: "Microcode SW error
detected. Restarting 0x0."
[Fix]
iwlwifi FWs from core56-54 release may fix this issue.
[Test Case]
This affects plenty of models:
* iwlwifi-9000-pu-b0-jf-b0-*:
- killer 1550*
- 9461/9462/9560
* iwlwifi-9260-th-b0-jf-b0-*:
- 9260
* iwlwifi-Q*-hr-b0-*:
- AX201
- AX1650*
* iwlwifi-Q*-jf-b0-*:
- 9560
* iwlwifi-cc-a0-*:
- AX200
While -59 fw is only used by 5.11-hwe kernel in Focal, they are tested
only against hwe-5.11. For iwlwifi-9* fw, they are used by kernel since
5.1, they're tested against 5.4/5.6/5.8 and 5.11 kernels.
Test steps:
- Connect both DUTs to the 5G wifi AP
- on DUT 1
- $ iperf3 -s -B 192.168.50.188
- on DUT 2
- $ iperf3 -c 192.168.50.188 -B 192.168.50.91 -t 6000
- After about 30 mins the wifi crashed with firmware related error
[Where problems could occur]
We have little info about each update of firmware blobs. So far we only
know that their revisions match those claimed by kernel driver and we
did not find other issues under the tests.
[Other Info]
Groovy 5.8 kernel supports -58 at max, and Hirsute has this already. So
only Focal is nominated for hwe-5.11 kernel support. For 5.13-oem, -63
fw is being SRU-ed in bug 1933415.
