/*

AdjustRate([I<KEYWORDS>])

=s Wifi

Sets the bit-rate for a packet.

=d

Sets the Wifi TXRate Annotation on a packet.

Regular Arguments:
=over 8

=item RATE 
Unsigned integer. Rate value is multiplied by 2 (i.e. 2
means 1 Mbps, 11 means 5.5 Mbps)

=back 8

=h rate read/write
Same as RATE Argument

=a AutoRateFallback, MadwifiRate, ProbeRate, ExtraEncap
