5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Arinzon <darinzon@xxxxxxxxxx>
[ Upstream commit 4ab138ca0a340e6d6e7a6a9bd5004bd8f83127ca ]
When sending TX packets, the meta descriptor can be all zeroes
as no meta information is required (as in XDP).
This patch removes the validity check, as when
`disable_meta_caching` is enabled, such TX packets will be
dropped otherwise.
Fixes: 0e3a3f6dacf0 ("net: ena: support new LLQ acceleration mode")
