SRU Justification:

[Impact]
Description of problem:

Within 24.04 an intel FVL Idea adapter flash fails through a FW smart component RPM install. The flash successfully completes on the firmware(NVM) and fails on the firmware(ROM). The process takes roughly thirty minutes and still fails.

Following this the NIC will not be recognized by the OS or RBSU until the next power cycle.

Version-Release number of selected component (if applicable):

Kernel 6.8.0-38-generic

How reproducible:

100% of the time

Steps to Reproduce:
1. Attempt to upgrade NIC (Intel Ethernet Converged Network Adapter X710-DA2 was used in my case) using upgrade located at https://support.hpe.com/connect/s/softwaredetails?language=en_US&collectionId=MTX-eeaaff922a754e17
2. Wait 30 minutes for upgrade to fail
3. Observe that NIC is no longer recognized
4. AC Power Cycle to bring the NIC back up

Actual results:

Upgrade fails and system requires a power cycle to use NIC again.

Expected results:

Upgrade succeeds

[Fix]
Additional info:

There is an upstream patch from Intel that remediates this issue, where the NIC successfully upgrades in a reasonable amount of time.

https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=8b9b59e27aa88ba133fbac85def3f8be67f2d5a8

I have patched the kernel, 6.8.0-38-generic, with the patch above and observed success.

[Test Plan]
Steps to Reproduce:
1. Attempt to upgrade NIC (Intel Ethernet Converged Network Adapter X710-DA2 was used in my case) using upgrade located at https://support.hpe.com/connect/s/softwaredetails?language=en_US&collectionId=MTX-eeaaff922a754e17
2. Wait 30 minutes for upgrade to fail
3. Observe that NIC is no longer recognized
4. AC Power Cycle to bring the NIC back up

Expected results:

Upgrade succeeds

[Where problems could occur]

The regression risk is low
