From: Sara Sharon Date: Thu, 17 Nov 2016 09:35:05 +0000 (+0200) Subject: iwlwifi: mvm: support new scan API X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9ba221b372c177b6908ff8c39b7b056538622ae1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: mvm: support new scan API For CDB devices we will want to configure scan parameters per band. Support the new scan API for now. Logic per band will be added in the future.
