From 1b499cb72f26bbf44f2fa158c2d1487730aae96a Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Sun, 24 Apr 2016 23:49:51 -0700 Subject: [PATCH] mwifiex: disable channel filtering feature in firmware As 2.4Ghz channels are overlapping, sometimes AP responds to probe request even if it's operating on neighbouring channel. Currently firmware drops those scan entries, as current channel doesn't match with APs channel. This patch enables MWIFIEX_DISABLE_CHAN_FILT flag in scan command to disable the feature so that better scan results will be received in 2.4Ghz band.
