PATCH 1 - Add MII-Lite PHY interface mode as defined by Broadcom for
their two-wire PHYs. It can be used with most Ethernet controllers
under certain limitations (no half-duplex link modes etc.).

PATCH 2 - Add MII-Lite PHY interface type

PATCH 3 - Activation of MII-Lite interface mode on Broadcom bcm5481x
PHYs

PATCH 4 - Fix the BCM54811 PHY initialization so that it conforms
to the datasheet regarding a reserved bit in the LRE Control
register, which must be written to zero after every device reset.
Also fix the LRE Status register reading, there is another bit to
be ignored on bcm54811.

I'm a bit lost why the first 3 patches are included in a series for net.
My naive reading is we didn't support this extra mode, now we do,
which sounds like a new feature.. Patch 4, sure, but the dependency
is not obvious.

I don't see the dependency either, at least not in an explicit way. Kamil, could patch #4 stand on its own and routed through "net" while patches 1-3 are routed through "net-next"?

Thanks
