Subject: mac802154: add basic support for monitor
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=38130c31ef50de1999983601e448db2b1bc1057c;p=linux.git

mac802154: add basic support for monitor

This patch adds basic support for monitor mode. Also change the open
call that we set the transceiver mac setting on an interface up. Futher
patches will add a better handling while interface up an interface.
