From 55556dd59dfc49e9429b058cf7138a6726c949c7 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Sat, 26 Nov 2016 01:28:05 +0100 Subject: [PATCH] bpf: drop useless bpf_fd member from cls/act After setup we don't need to keep user space fd number around anymore, as it also has no useful meaning for anyone, just remove it.
