[ns] removing packet segmentation at 802.11 level

Hallo everybody.

Lets have a look at this trace.

s 73.019352000 _2_ MAC  --- 30994 cbr 1072 [13a 3 2 800] ------- [2:1 3:0 32
3] [10330] 0 0
s 73.027938133 _3_ MAC  --- 0 ACK 38 [0 2 0 0]
s 73.027988267 _2_ MAC  --- 30995 cbr 572 [13a 3 2 800] ------- [2:1 3:0 32
3] [10331] 0 0

Actually I have CBR sources sending  64 bytes lenght packets at application
level.

Given that I have UDP at L4 (overhead 20 bytes) and takin into account that
the PHY overhead of the MAC 802.11 is 52 bytes, it is clear that I  am not
controlling a segmentation at 1000 bytes. I can I remove this constraint?

Thank you in advance
