Hi,
This diffs discards frame largers than 2500 bytes.
Tested on my machine:
urtw0 at uhub0 port 2 "Realtek RTL8187B" rev 2.00/2.00 addr 2
urtw0: RTL8187B rev E, address 00:16:44:9f:76:cb
urtw0 at uhub0 port 2 "Realtek RTL8187B" rev 2.00/2.00 addr 2
urtw0: RTL8187B rev E, address 00:16:44:9f:76:cb
I tested with both normal traffic,NFS, and scp.

No regressions here.
I'd really appreciate feedback on this, since I'm not familiar
with the wifi stack. Any Wifi guru around :-) ?

Please test this on as many urtw(4) devices as you can.
