Subject: iwlwifi: pcie: remove the active field in struct iwl_txq
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=de74c455fd991024be76a535df4d66e96af3896e;p=openwrt%2Fstaging%2Fblogic.git

iwlwifi: pcie: remove the active field in struct iwl_txq

We already have queue_used in the transport - we can
use it instead.
