Message-Id: <1462285862-30946-3-git-send-email-fw@strlen.de>

Subject: [PATCH net-next 2/5] drivers: replace dev->trans_start accesses with dev_trans_start
a trans_start struct member exists twice:
- in struct net_device (legacy)
- in struct netdev_queue
Instead of open-coding dev->trans_start usage to obtain the current
trans_start value, use dev_trans_start() instead.
This is not exactly the same, as dev_trans_start also considers
the trans_start values of the netdev queues owned by the device
and provides the most recent one.
For legacy devices this doesn't matter as dev_trans_start can cope
with netdev trans_start values of 0 (they are ignored).
This is a prerequisite to eventual removal of dev->trans_start.

Checkpatch complains about Lines > 80 but I find line break more ugly.
