rtl93xx has two distribution algorithm slots that are shared among
multiple trunks.
Each of this slot can be configured to handle L2 and/or L3 packets
Hardware can also be configured to support layer3+4 but that is not
802.3ad compliant. With this commmit I want to focus on getting
layer2 and layer2+3 initialized in two slots.
When a new LAG group is created, depending on the xmit_hash_policy
configuration a slot will be configured in LAG table entry
SPA and VLAN bits made the switch to always choose same link for all
connections which completely dismisses point of Link aggregation.
So avoid these and stick to SMAC + DMAC for L2 packets and
SMAC + DMAC + SIP + DIP for L3 packets
