Subject: broadcom-wl: simplify processing of 'hwmode'
X-Git-Tag: reboot~8673
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=aa6a5baf88a861aef7d3a0ac20a6528180dfd9f3;p=openwrt%2Fstaging%2Fnoltari.git

broadcom-wl: simplify processing of 'hwmode'

Default gmode to "GOnly" unless explicitly overwridden.  This corrects
processing for 11ng to specify "GOnly" for gmode instead of "Auto"
(which translated to "bg").
