[PATCH net-next 00/12] net: dsa: support for inband management of switches

[Luke Howard]

This patch set shephards a series of commits made by Andrew Lunn
and others to support inband management of DSA switches. [1]

Specifically, it allows the switch itself to be managed using
DSA tagged frames instead of MDIO. MDIO is typically required
to enable inband management. An implementation is included for
the qca8k driver.

This is patch set one of four: the remaining sets add support
for the Remote Management Unit (RMU) in the mv88e6xxx, and then
general and mv88e6xxx support for "inband-only" mode where MDIO
is unavailable on the hardware.

Note: the patch to validate the source trunk against lags_len
was previously submitted and rejected, but I am including it as
the issue has been triggered when running in inband mode.
