>1563) a substitute header should be added. This substitute header is set using an LLC header
described in RFC 1042 (default option). This option can be overridden by using the header used
in 802.1H protocol. The list of EtherTypes which are going to use the 802.1H header should be
set in the LLC Encapsulation page.
This override option should be used when the WBS is used in non-802.3 Ethernet networks
(FDDI, Token Ring, etc.)
The list of EtherTypes is used also to recover the frames in the uplink, as they are received with
an LLC header from the 802.11 link.
LLC encapsulation
For each EtherType that is valid in this table, the
802.1H bridge tunnel encapsulation format is used.
Otherwise, RFC1042 applies.
