[SRU][Groovy][PULL] update ENA driver for LLQ

[Kamal Mostafa]

BugLink: https://bugs.launchpad.net/bugs/1890845

This pull request update the Amazon ENA driver in focal-generic with all
upstream commits from mainline and net-next, through:

  0e3a3f6dacf0 net: ena: support new LLQ acceleration mode

The commits are all cherry-picks or light context backports; touches only the
ENA driver.

The driver update provides new hardware support, fixes, and features required
to support future ENA devices at AWS.

I have smoke-tested the build; no problems noted.
