From e8a0464cc950972824e2e128028ae3db666ec1ed Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 17 Jul 2008 00:34:19 -0700 Subject: netdev: Allocate multiple queues for TX. alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.
