Merge branch 'net-phy-add-and-use-genphy_c45_an_config_an'
Heiner Kallweit says:
====================
net: phy: add and use genphy_c45_an_config_an
This series adds genphy_c45_an_config_an() and uses it in the
marvell10g diver. In addition patch 4 aligns the aneg configuration
with what is done in genphy_config_aneg().
v2:
- in patch 2 changed function name to genphy_c45_an_config_aneg
- in patch 3 add a comment regarding 1000BaseT vendor registers
v3:
- rebase patch 3
====================
