1. Add common code for stopping queue. 2. No need to call netif_stop_queue followed by netif_wake_queue (and infact a netif_start_queue could have been used instead), instead call stop_queue if required, and remove code under USE_GTS macro. 3. There is no need to check for netif_queue_stopped, as the network core guarantees that for us (I am sure every driver could remove that check, eg e1000 - I have tested that path a few billion times with about a few hundred thousand qstops but the condition never hit even once).

The e1000 driver stores the content of the PCI resources into unsigned long's before ioremapping. This breaks on 32 bits platforms that support 64 bits MMIO resources such as ppc 44x. This fixes it by removing those temporary variables and passing directly the result of pci_resource_start/len to ioremap. The side effect is that I removed the assignments to the netdev fields mem_start, mem_end and base_addr, which are totally useless for PCI devices.

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.

Since kernel virtual memory is not a problem on 64-bit systems, there is no reason to use our own 2-layer page mapping scheme for large kernel queue buffers on such systems. Instead, map the page list to a single virtually contiguous buffer with vmap(), so that can we access buffer memory via direct indexing. Signed-off-by: NMichael S.

Now virtnet_open on cpu 2 managed to execute napi_enable and disable_cb but did not execute rx_schedule. Meanwhile on cpu 0 skb_recv_done was called by vring_interrupt, executed netif_rx_schedule_prep, which succeeded and therefore called disable_cb. This triggered the BUG_ON, as interrupts were already disabled by cpu 2. I think the proper solution is to make the call to disable_cb depend on the atomic update of NAPI_STATE_SCHED by using netif_rx_schedule_prep in the same way as skb_recv_done.

This patch converts cpmac to the new Fixed PHY infrastructure, though it doesn't fix all the problems with that driver. I didn't even bother to test this patch to compile, because cpmac driver is broken in several ways: 1. This driver won't compile by itself because lack of its header describing platform data; 2. It assumes that fixed PHYs should be created by the ethernet driver. It is wrong assumption: fixed PHYs creation is platform code authority, driver must blindly accept bus_id and phy_id platform data variables instead. Also, it seem that that driver doesn't have actual in-tree users, so nothing to fix further. The main purpose of that patch is to get rid of the following Kconfig warning: scripts/kconfig/conf -s arch/powerpc/Kconfig drivers/net/Kconfig:1713:warning: 'select' used by config symbol 'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX' Signed-off-by: NAnton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: NKumar Gala <galak@kernel.crashing.org>
