Subject: [PATCH] batman-adv: fix potential kernel paging errors for unicast
 transmissions
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8

There are several functions which might reallocate skb data. Currently
some places keep reusing their old ethhdr pointer regardless of whether
they became invalid after such a reallocation or not. This potentially
leads to kernel paging errors.

This patch fixes these by refetching the ethdr pointer after the
potential reallocations.
