Message-ID: <20121204223504.GD4428@liveoak> (sfid-20121204_233512_993448_A6658A5F) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-wireless-owner@vger.kernel.org List-ID: Perhaps I am missing something, but is there a way for mac80211 drivers to be notified of timeouts on their tx queues, or does each have to implement its own watchdog? net_device_ops provides an ndo_tx_timeout hook for netdevices, but mac80211 seems not to implement this hook. Bob Copeland pointed me at some history that seems to indicate mac80211 dropped the ndo_tx_timeout functionality because net_device lacked multi-queue support: http://marc.info/?l=linux-wireless&m=117449935910306 Looks like net_device has multi-queue support now, should we bring back ieee80211_tx_timeout or something similar? Thanks Jason
