The 2.6.32.4 kernel got added MQ support back. I've tried to backport this and this is what I have so far: http://bombadil.infradead.org/~mcgrof/tmp/compat-wireless-2.6.32.4-rc1.tar.bz2 Not sure about the select queue stuff yet though. Reports of uses of ath9k (./scripts/driver-select ath9k) on 2.6.23..2.6.26 would be appreciated. Luis --- 18-multiqueue.patch --- The 2.6.23 kernel added multiqueue support. That release relied on the on the notion of struct net_device_subqueue attached to the netdevice struct as an array. The 2.6.27 renamed these to struct netdev_queue, amogst other changes. For kernels 2.6.23..2.6.26 then we backport MQ support by using the equivalent calls on the struct netdev_queue to the struct net_device_subqueue. For older kernels than 2.6.23 we can only stop all the queues then. --- a/net/mac80211/util.c 2010-01-20 18:35:04.000000000 -0800 +++ a/net/mac80211/util.c 2010-01-20 18:34:11.000000000 -0800 @@ -287,7 +287,13 @@ rcu_read_lock(); list_for_each_entry_rcu(sdata, &local->interfaces, list) +#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,27)) netif_tx_wake_queue(netdev_get_tx_queue(sdata->dev, queue)); +#elif (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,23)) + netif_start_subqueue(sdata->dev, queue); +#else + netif_wake_queue(sdata->dev); +#endif rcu_read_unlock(); } @@ -322,7 +328,13 @@ rcu_read_lock(); list_for_each_entry_rcu(sdata, &local->interfaces, list) +#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,27)) netif_tx_stop_queue(netdev_get_tx_queue(sdata->dev, queue)); +#elif (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,23)) + netif_stop_subqueue(sdata->dev, queue); +#else + netif_stop_queue(sdata->dev); +#endif rcu_read_unlock(); } -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
