From 95357907ae73a8039c2106897ee2694f26ac3caf Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Fri, 16 Sep 2016 22:36:12 +0200 Subject: [PATCH] mlx4: fix XDP_TX is acting like XDP_PASS on TX ring full The XDP_TX action can fail transmitting the frame in case the TX ring is full or port is down. In case of TX failure it should drop the frame, and not as now call 'break' which is the same as XDP_PASS.
