From 377cf82d66ea43f3d3cb82c2563e65b5c12c9bfd Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 31 Jan 2008 03:46:12 -0800 Subject: [PATCH] [RAW]: Family check in the /proc/net/raw[6] is extra. Different hashtables are used for IPv6 and IPv4 raw sockets, so no need to check the socket family in the iterator over hashtables. Clean this out. Signed-off-by: Denis V.
