[PATCH 2/4] staging: wlan-ng: use GENMASK macro in different defines of p80211hdr.h

[Sergio Paracuellos <sergio.paracuellos@gmail.com>]

This patch replace actual mask stuff using BIT macros with 
or operators to make use of GENMASK macro which simplifies 
code clearity and readibility.

It applies for defines included in p80211hdr.h header file.
