Subject: iwlwifi: mvm: support moving to mgmt tid
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c65f4e03fc46c646f81cc659e501969ca48c3220;p=openwrt%2Fstaging%2Fblogic.git

iwlwifi: mvm: support moving to mgmt tid

For a000 FW moved to 15 as management TID.
The change for us is fairly local - translate old TID to 15
when enabling and disabling a queue, and make sure to cover
it also on TX responses.
