2008-12-03bnx2: Add workaround to handle missed MSI.Michael Chan
The bnx2 chips do not support per MSI vector masking. On 5706/5708, new MSI address/data are stored only when the MSI enable bit is toggled. As a result, SMP affinity no longer works in the latest kernel. A more serious problem is that the driver will no longer receive interrupts when the MSI receiving CPU goes offline. The workaround in this patch only addresses the problem of CPU going offline. When that happens, the driver's timer function will detect that it is making no forward progress on pending interrupt events and will recover from it. Eric Dumazet reported the problem. We also found that if an interrupt is internally asserted while MSI and INTA are disabled, the chip will end up in the same state after MSI is re-enabled. The same workaround is needed for this problem. Signed-off-by: Michael Chan <mchan@broadcom.com> Tested-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-12bnx2: fix poll_controller to pass proper structures and check all rx queuesNeil Horman
Fix bnx2 so that netpoll works properly. Specifically: 1) Fix parameters to bnx2_interrupt to be a struct bnx2_napi rather than a struct net_device 2) Fix poll_controller method to check every queue in the rx case so frames aren't missed Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more.

Before, the driver would not care about the return codes from pci_map_* functions. This could be potentially dangerous if a mapping failed. Now, we will check all pci_map_* calls.

2008-08-14bnx2: Reinsert VLAN tag when necessary.Michael Chan
In certain cases when ASF or other management firmware is running, the chip may be configured to always strip out the VLAN tag even when VLAN acceleration is not enabled.

2008-06-12net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller
If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.
