From 366e4adc0f9ef33f56c62f980a7d83775e64abd0 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 26 Aug 2006 16:50:20 -0700 Subject: [PATCH] [IPV6]: Fix routing by fwmark Fix mark comparison, also dump the mask to userspace when the mask is zero, but the mark is not (in which case the mark is dumped, so the mask is needed to make sense of it).
