CPSW: Host to Ethernet Checksum Generation with VLAN ADD/Remove

Details:

When the CPSW host to ethernet checksum generation is enabled on HW and a VLAN tag is added or removed on Ethernet egress, a packet from host to ethernet is corrupted and sent as garbage with a GOOD CRC – which is not acceptable.

Workaround(s):

VLAN tags must not be added or removed on Ethernet egress for packets that have a generated checksum.
