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.
