Reassembles 802.11 fragments.

=d 

This element reassembles 802.11 fragments and pushes the reassembled
packet out when the last fragment is received. It does not affect
packets that are not fragmented, and passes them through its output
unmodified.  In accordance with the 802.11 spec, it supports a single
packet per SA.
