Also I wonder what should be the max mtu.

2304, I think, as that's
synonym sMaxMsduLng Integer = 2304; /* max octets in an MSDU */

But maybe I'm interpreting the spec wrongly?

Yes, I think so. ;)

I am pretty sure this is the maximum _fragment_ size.
But each packet (which max size is defined by the MTU) can
be fragmented. I don't know if there's a limit on the max
number of frags.

No it's not. How about reading the standard.. ;-) Take a look at how
MSDU and MPDU are defined.. MSDU can be fragmented into smaller MPDUs,
but the limit here is indeed for MSDU, not MPDU. In other words,
fragmentation in IEEE 802.11 is different from fragmentation in IP and
it is also used for different purpose.
