From ebb762f27fed083cb993a0816393aba4615f6544 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 23 Nov 2011 02:12:51 +0000 Subject: net: Rename the dst_opt default_mtu method to mtu We plan to invoke the dst_opt->default_mtu() method unconditioally from dst_mtu(). So rename the method to dst_opt->mtu() to match the name with the new meaning. Signed-off-by: Steffen Klassert Signed-off-by: David S.
