stable inclusion from stable-v6.6.8 commit 2cc8ffc3ad31b5618ad6b34450274d3a9817ce1f bugzilla: https://gitee.com/openeuler/kernel/issues/I99K53
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
