Since commit 0c4b2d370514cb4f3454dd3b18f031d2651fab73
("net: remove VLAN_TAG_PRESENT"), the kernel no longer sets the DEI/CFI
bit in __vlan_hwaccel_put_tag to indicate the presence of a VLAN tag.
Update the openvswitch documentation which still contained an outdated
reference to this mechanism.

Unlike a TCP packet with source and destination ports 0, an
