If you have hostap on both sides, you probably can set the access point
with the new firmware to use non-standard frames.  That's bit 2 in
get_wds. So if "iwpriv wlan0 getwds_type" gives 4, use "iwpriv wlan0
wds_type 0".

If Linksys WAP-11 uses tertiary firmware it probably supports standard
WDS.  Most access points load tertiary firwmare in RAM, so the version of
the secondary firmware doesn't matter.
