Merge branch 'dsa-netconsole'

Florian Fainelli says:

====================
net: GENET, SYSTEMPORT and DSA netconsole

This patch series adds support for netconsole in the GENET, SYSTEMPORT and DSA
drivers.

A small refactoring to the DSA transmit path is required to avoid duplicating
the dsa_netpoll_send_skb() into each and every tagging protocol supported.

Testing on e.g: mv643xx_eth and/or e1000e would be much appreciated!

Changes in v2:

- properly disable/enable interrupts in GENET and SYSTEMPORT

- pass the reallocated SKB back to dsa_slave_xmit() in case a tag protocol had to
  alter the original SKB
