Subject: [PATCH v2 net-next 0/2]  net: dsa: lan9303: Learn addresses on CPU port when bridged

When CPU transmit directly to port using tag, the LAN9303 does not
learn MAC addresses received on the CPU port into the ALR table.
ALR learning is performed only when transmitting using ALR lookup.

Solution:
If the two external ports are bridged and the packet is not STP BPDU,
then use ALR lookup to allow ALR learning on CPU port.
Otherwise transmit directly to port with STP state override.

The first patch moves struct lan9303 to include/linux/dsa/lan9303.h in
order to prepare for the second patch. 

Changes v1 -> v2:
 - new file: include/linux/dsa/lan9303.h instead of include/linux/lan9303.h
 - include linux/if_ether.h in include/linux/dsa/lan9303.h
 - renamed lan9303_tx_use_arl to lan9303_xmit_use_arl for consistency.
 - removed inline keyword to lan9303_xmit_use_arl
