When the VXLAN ports are added and removed, the messaging was giving some
bogus index info, the port was always '0' for the delete, and the message
text style didn't match other messages in the driver.  Also, there was an
over-use of the tertiary statement which made reading a little harder
than necessary.

If transmit VLAN HW offloads are disabled then the network stack sends up
an skb with the protocol set to 8021q. In that case to get the correct
checksum offloads we have to reset the skb protocol to the encapsulated
ethertype.

Since IP fragments (datagram) have no upper protocols (L3 IP packets),
