From: Johannes Berg Date: Fri, 26 May 2017 11:11:44 +0000 (+0200) Subject: iwlwifi: mvm: use proper CDB check in PHY context modify X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=91109f42d0ad0c0c282d1fa1257a1548977aa895;p=openwrt%2Fstaging%2Fblogic.git iwlwifi: mvm: use proper CDB check in PHY context modify When the firmware supports CDB, PHY contexts cannot be modified to change their band, but need to be added/remove instead. Instead of relying on iwl_mvm_has_new_tx_api(), check the right FW capa flag IWL_UCODE_TLV_CAPA_BINDING_CDB_SUPPORT and remove the comment.
