Subject: veth: remove unused list
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3717746ef8b5a9279281b5d318496710984ed739;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

veth: remove unused list

The veth network device is stored in a list in the netdev private.
AFAICS, this list is never used so I removed this list from the code.
