Alexandre, Right, so it doesn’t sound like you have any reason to be different from RFC2464. Just reference or copy that text (section 5, rfc2464).

There is no necessarily any bridging between the 802.11-OCB interface and other interface, neither bridging between the multiple 802.11-OCB interfaces that might be present in the same computer. > > Do you assume bridging of 802.11-OCB interface to Ethernet interface is always there? > > Note: I also heard many comments suggesting that EAL is akin to 'bridging'.
