PS3: gelic: Add support for dual network interface
Add support for dual network (net_device) interface so that ethernet and wireless can own separate ethX interfaces. V2 - Fix the bug that bringing down and up the interface keeps rx disabled. - Make 'gelic_net_poll_controller()' extern , as David Woodhouse pointed out at the previous submission. - Fix weird usage of member names for the rx descriptor chain V1 - Export functions which are convenient for both interfaces - Move irq allocation/release code to driver probe/remove handlers because interfaces share interrupts. - Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb() as the interfaces share the hardware rx queue. - Add gelic_port struct in order to abstract dual interface handling - Change handlers for hardware queues so that they can handle dual {source,destination} interfaces. - Use new NAPI functions This is a prerequisite for the new PS3 wireless support. Signed-off-by: Jeff Garzik <jeff@garzik.org>
