Subject: net: xmit_list() becomes dev_hard_start_xmit().
X-Git-Tag: v3.18-rc1~52^2~190^2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8dcda22a5d0abaf347b21b057655f3809b91639d;p=karo-tx-linux.git

net: xmit_list() becomes dev_hard_start_xmit().

Now fundamentally we can process lists of SKBs as cheaply
as single packets.
