From: Amitkumar Karwar Date: Wed, 25 Jan 2012 04:50:25 +0000 (-0800) Subject: mwifiex: update BSS parameters in dump_station_info() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c4f3b9725ed476adbcaf1c49d882ab541bc4214c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git mwifiex: update BSS parameters in dump_station_info() This enables user to check beacon interval, DTIM period, short slot time and short preamble information using "iw dev mlan0 link" command when station is in connected state.
