10 Kernel support for multiqueue devices is always present.
12 Section 1: Base driver requirements for implementing multiqueue support
13 -----------------------------------------------------------------------
15 Base drivers are required to use the new alloc_etherdev_mq() or
16 alloc_netdev_mq() functions to allocate the subqueues for the device. The
17 underlying kernel API will take care of the allocation and deallocation of
18 the subqueue memory, as well as netdev configuration of where the queues
21 The base driver will also need to manage the queues as it does the global
22 netdev->queue_lock today. Therefore base drivers should use the
23 netif_{start|stop|wake}_subqueue() functions to manage each queue while the
24 device is still operational. netdev->queue_lock is still used when the device
25 comes online or when it's completely shut down (unregister_netdev(), etc.).
