Subject: [PATCH v1 net 4/4] net: ena: Fix XDP redirection error
From: David Arinzon <darinzon@...zon.com>
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")
