Hi experts,
I have some trouble to understand the vlan of ALE. There is a bit VID_INGRESS_CHECK in ALE port control register, it says
"VLAN ID Ingress Check. If VLAN not found then drop the packet. Packets with an unknown (default) VLAN will be dropped.", but after I set this
bit to 1, emac port can still receive non vlan-tagged packets. So what exactly does this bit do ? Thanks.
