From 486b51d3706c5493b6c50992eaaafc44e628a7ed Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Mon, 14 Jan 2008 22:59:59 -0800 Subject: [PATCH] [ARP]: Remove overkill checks from neigh_param_alloc. Valid network device is always passed into neigh_param_alloc, so remove extra checking for dev == NULL. Additionally, cleanup bogus netns assignment. Signed-off-by: Denis V.
