From aa0010f880ab542da3ad0e72992f2dc518ac68a0 Mon Sep 17 00:00:00 2001 From: Amerigo Wang Date: Sun, 11 Nov 2012 21:52:33 +0000 Subject: net: convert __IPTUNNEL_XMIT() to an inline function __IPTUNNEL_XMIT() is an ugly macro, convert it to a static inline function, so make it more readable. IPTUNNEL_XMIT() is unused, just remove it. Cc: David S. Miller Signed-off-by: Cong Wang Signed-off-by: David S.
