Subject: iwlwifi: mvm: go to umac scan even if lmac tlv bit is on
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b975e55adcda54aa778e9b4f5eb162891f952cde;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

iwlwifi: mvm: go to umac scan even if lmac tlv bit is on

LMAC TLV bit may be on in FWs that support UMAC scan; so check
for UMAC TLV bit first.
