Subject: [NETNS]: Make arp code network namespace consistent.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2db82b534bd52b349f1b2ab3e63aa40ca0e466ab;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[NETNS]: Make arp code network namespace consistent.

Some calls in the arp.c have network namespace as an argument. Getting
init_net inside these functions is simply inconsistent. Fix this.
