Public bug reported:
SRU Justification
[Impact]
A stable update from LP: #1853180 was carried forward to the Lunar 6.2
and Mantic 6.5 kernels. As it did not cause a conflict it likely escaped
notice when the Jammy AWS kernel was forward ported. Commit
05785adf6e570a068adf0502b61fe2b521d7f0ca ('net: ena: fix default tx
interrupt moderation interval') from v5.5 set
ENA_INTR_INITIAL_TX_INTERVAL_USECS to 64, but was then overwritten
during the forward port rebase by patch ('UBUNTU: SAUCE: net: ena: fix
too long default tx interrupt moderation interval'). Reverting this
patch will restore the AWS ENA driver to upstream default of 64.
[Test Plan]
AWS tested.
[Regression potential]
Network connections could exhibit adverse jitter times.
