Kurt Kanzenbach says:

This series contains some cosmetics for the flex filter code. The fixes have
been merged separately via -net already.

The following are changes since commit ddb2d2a8e81474f61f2c6f0b9b3b4fb0d90677d0:
  Merge branch 'net-eee-network-driver-cleanups'
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 1GbE

Kurt Kanzenbach (3):

[PATCH net-next 2/3] igc: Use netdev printing functions for flex filters

[Tony Nguyen]

From: Kurt Kanzenbach <kurt@linutronix.de>

All igc filter implementations use netdev_*() printing functions except for
the flex filters. Unify it.

From: Kurt Kanzenbach <kurt@linutronix.de>
