Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net
Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to net, ixgbe and e1000e.
David provides compiler fixes for e1000e.
Don provides a fix for ixgbe to resolve a compile warning.
John provides a fix to net where it is useful to be able to walk all
upper devices when bringing a device online where the RTNL lock is held.
In this case, it is safe to walk the all_adj_list because the RTNL lock is
used to protect the write side as well. This patch adds a check to see
if the RTNL lock is held before throwing a warning in
netdev_all_upper_get_next_dev_rcu().
