From b4ce92775c2e7ff9cf79cca4e0a19c8c5fd6287b Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 13 Nov 2007 21:33:32 -0800 Subject: [IPV6]: Move nfheader_len into rt6_info The dst member nfheader_len is only used by IPv6. It's also currently creating a rather ugly alignment hole in struct dst. Therefore this patch moves it from there into struct rt6_info. It also reorders the fields in rt6_info to minimize holes.
