From: Greg Kroah-Hartman
Date: Thu Apr 20 2017 - 02:41:07 EST


3.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Todd Fujinaka <todd.fujinaka@xxxxxxxxx>

commit 5bc8c230e2a993b49244f9457499f17283da9ec7 upstream.

i210 and i211 share the same PHY but have different PCI IDs. Don't
forget i211 for any i210 workarounds.
