[PATCH 0/2][l/m linux-aws] AWS: Set ENA_INTR_INITIAL_TX_INTERVAL_USECS to 64

SRU Justification

[Impact]

An 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.
