Title:
[AWS] Fix interrupt mappings which are set to a bad default after
certain ENI operations

New
Status in linux-aws source package in Focal:

Status in linux-aws source package in Jammy:

Status in linux-aws source package in Noble:

Status in linux-aws source package in Oracular:

Bug description:
SRU Justification:
[Impact]
Interrupt mapping is set to a bad default after certain ENI operations
After using ethtool to update the (rx) ring buffer settings on an ENI,
the interrupt CPU affinity for all tx-rx queues is reset to a bad
default - CPU 0-31 - even if the ENI is on a different CPU socket
(NUMA node). Another operation that causes the interrupt mapping to be
reset to CPU 0-31 is moving an interface to a network namespace.
[Fix]
ENA driver version 2.12.3g. They mentioned that this commit in the ENA
code looks like it addresses the bug: https://github.com/amzn/amzn-
drivers/commit/ed7754cdf6ca0d4fb3d76906abc17718cc3ffa23
It's included starting in driver version 2.12.0.
I have back ported the patch from the AWS OOT driver, as well as any
existing prerequisites needed.
[Test Plan]
I have tested this, as has AWS.
[Where problems could occur]
As this is an Ubuntu Sauce patch, if these changes make their was into
the stable trees, or any patches touching this area of code, they may
cause merge conflicts, or changes in behaviour which are unexpected.
