From 2cc8ffc3ad31b5618ad6b34450274d3a9817ce1f Mon Sep 17 00:00:00 2001 From: David Arinzon Date: Mon, 11 Dec 2023 06:28:01 +0000 Subject: [PATCH] net: ena: Fix XDP redirection error [ 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.
