From d4ac05ff3697e036dcb0e2e284c5f7eb77cc0966 Mon Sep 17 00:00:00 2001 From: Jiri Benc Date: Tue, 16 Feb 2016 21:58:57 +0100 Subject: vxlan: introduce vxlan_hdr Currently, pointer to the vxlan header is kept in a local variable. It has to be reloaded whenever the pskb pull operations are performed which usually happens somewhere deep in called functions. Create a vxlan_hdr function and use it to reference the vxlan header instead. Signed-off-by: Jiri Benc Signed-off-by: David S.
