From: David S. Miller Date: Wed, 4 May 2011 02:45:15 +0000 (-0700) Subject: ipv4: Renamt struct rtable's rt_tos to rt_key_tos. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=475949d8e86bbde5ea3ffa4d95e022ca69233b14;p=linux-beck.git ipv4: Renamt struct rtable's rt_tos to rt_key_tos. To more accurately reflect that it is purely a routing cache lookup key and is used in no other context. Signed-off-by: David S.
