Merge branch 'net-phy-Reduce-duplication' 



Florian Fainelli says:

====================
net: phy: Reduce duplication

This patch series reduces the duplication among 10G PHY drivers that just
essentially stub most functions, but do that while replicating what the existing
generic functions do.

Changes in v3:

- removed unused "reg" variable in teranetics.c
- fixed subject for patch 5 since we actually use gen10g_no_soft_reset()

Changes in v2:

- rename gen10g_soft_reset() to gen10g_no_soft_reset() to better illustrate
  what it does (or does not)
- removed stray comment in marvell10g.c
====================
