From: Eliad Peller Date: Thu, 22 Nov 2012 16:06:16 +0000 (+0200) Subject: wl18xx: increase MAX_CHANNELS_5GHZ X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a1c720c63be74bbfe416fa085d0783348e4d69b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git wl18xx: increase MAX_CHANNELS_5GHZ Some regdomains have more than 23 valid 5ghz channels, so 18xx's MAX_CHANNELS_5GHZ was increased to 32. Since now we have different max 5ghz channels values for wl12xx and wl18xx, add a new wl->max_channels_5ghz field, and use it for scan channels configuration.
