/**
\brief A SnrEval for the 802.11b protocol

Subclass of SnrEval. Basically the same except for some extra
parameters of 802.11 and the duration of the packet that has to be
computed differently as the modualtion of header and data part of the
packet are different. This module forms a physical layer together with
the Decider80211 module. The resluting physical layer is intended to
be used together with the Mac80211 module.
