From f5737cbadb7d07c4f71fc5f073ccc7d8d8985a8f Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Fri, 3 May 2019 17:01:36 +0200 Subject: [PATCH] net: use indirect calls helpers for ptype hook This avoids an indirect call per RX IPv6/IPv4 packet. Note that we don't want to use the indirect calls helper for taps. Signed-off-by: Paolo Abeni Signed-off-by: David S.
