staging: wlan-ng: use GENMASK macro in different defines of p80211hdr.h
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. Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
