* | ixgbe: fix bug with napi add before request_irqJesse Brandeburg2009-03-141-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Occasionally if the driver was loaded in a system that didn't support MSI-X or MSI and was on a shared interrupt, the driver would then panic in NAPI on the first shared interrupt because we hadn't called napi_add yet. Solution: call napi_add before calling request_irq Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

* | ixgbe: Fix interrupt configuration for 82599Jesse Brandeburg2009-03-141-21/+43
| | | | | | | | | | | | | | | | | | | | | | | | The interrupt models using EITR have changed in 82599. The way the register is laid out, the change is transparent to some of the existing code. However, some of it isn't. This patch fixes all the cases where EITR handling is different than 82598.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | it was pointed out on the list that ixgbe was failing when using 64kB pages and large 16kB MTU. since with a 64kB PAGE_SIZE MAX_SKB_FRAGS = 3, the way the driver was configuring page usage was assuming 2kB is half a page, and was only ever dmaing that much data to a half page. (16kB - header size) / 2048 = 7 or 8 pages, which would far exceed 3 adjust the driver to account for these large pages, the hardware can support DMA to up to 16kB for each descriptor.

* | ixgbe: fix for 82598 Si errata causing buffer overflowDon Skidmore2009-02-211-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The failure happens when an interrupt occurs and the driver is reading EICR. This read will cause a clear-by-read which leads to two TLP being inserted in the PCIe retry buffer leading to an overflow of the buffer and corruption of TLPs. The solution is different depending where the reading of EICR takes place. For ixgbe_msix_lsc() since we are in MSIX mode and know OCD is enabled a clear-by-write is done instead of the normal clear-by-read. For ixgbe_intr() 0xffffffff is written to EIMC before the read, masking the interrupts.

* | ixgbe: Fix usage of netif_*_all_queues() with netif_carrier_{off|on}()PJ Waskiewicz2008-11-161-3/+3
| | | | | | | | | | | | | | | | | | | | netif_carrier_off() is sufficient to stop Tx into the driver. Stopping the Tx queues is redundant and unnecessary. By the same token, netif_carrier_on() will be sufficient to re-enable Tx, so waking the queues is unnecessary.

* | netdevice: safe convert to netdev_priv() #part-1Wang Chen2008-11-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

* | drivers/net: Kill now superfluous ->last_rx stores.David S. Miller2008-11-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | We cannot select INTEL_IOATDMA in Kconfig as soon as MYRI10GE or IXGBE is enabled since the former is not available on all architectures. Just use a Kconfig bool {IXGBE,MYRI10GE}_DCA set to =y when DCA support can actually be built.
