Replace the previously used extension of IEEE 802.11 managed Ethertype 89-0d (originally added for Remote Request/Response in IEEE 802.11r) with Ethertype 88-b7 (OUI Extended EtherType) for FT inter-AP communication. The new design uses a more properly assigned identifier for the messages. This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP), and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH protocol. This breaks backward compatibility, i.e., hostapd needs to be updated on all APs at the same time to allow FT to remain functional. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>
