Hi all,

This was long overdue, with this patch series, the b53 driver now
turns on Broadcom tags except for 5325 and 5365 which use an older
format that we do not support yet (TBD).

First patch is necessary in order for bgmac, used on BCM5301X and Northstar
Plus to work correctly and successfully send ARP packets back to the requsester.

Second patch is actually a bug fix, but because net/master and net-next/master
diverge in that area, I am targeting net-next/master here.

Finally, the last patch enables Broadcom tags after checking that the CPU port
selected is either, 5, 7 or 8, since those are the only valid combinations
given currently supported HW.

Florian Fainelli (3):
  net: bgmac: Pad packets to a minimum size
  net: dsa: b53: Stop using dev->cpu_port incorrectly
  net: dsa: b53: Turn on Broadcom tags

David, I need to respin patch 2 and 3 since I squashed an incorrect hunk
into patch 2 which should have been in patch 3, thus breaking bisectability.
