Linus Walleij c990f6e156 linux: generic: net: dsa: mv88e6xxx LED support
This solution that is needed for some routers to provide proper
LED activity when controlled directly by the MV88E6xxx switch,
has just been merged in upstream Linux.

Make this patch 901 as other backports from earlier kernels
are in patch 896 and this is the first free number after
that.

Patch offsets in pending patches are augmented as part of
the refresh.

Subject: [RFC net-next 7/7] net: dsa: mv88e6xxx: Request assisted learning on CPU port

While the hardware is capable of performing learning on the CPU port,
it requires alot of additions to the bridge's forwarding path in order
to handle multi-destination traffic correctly.
Until that is in place, opt for the next best thing and let DSA sync
the relevant addresses down to the hardware FDB.
