From ab6e3af7fc94d3c04e13f468c56c097f88644a7c Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Thu, 20 Feb 2014 17:07:44 +0000 Subject: [PATCH] kernel/3.10: improve fq_codel hashing for 6in4 6to4 801.ad and IPIP cases This is a backport of code to improve the quality of fq_codel hashing for 3.10 for some encapsulated protocols. Not needed in 3.11 and later.
