Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM. Removing this needs deeper surgery.

VMWare reports that the e1000 driver has a bug when bringing down the interface, such that interrupts are not disabled in the hardware but the driver stops reporting that it consumed the interrupt. The fix is to set the driver's "down" flag later in the routine, after all the timers and such have exited, preventing the interrupt handler from being called and exiting early without handling the interrupt.

Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.

Net drivers in general have an issue where timers fired by mod_timer or work threads with schedule_work are running outside of the rtnl_lock. With no other lock protection these routines are vulnerable to races with driver unload or reset paths. The longer term solution to this might be a redesign with safer locks being taken in the driver to guarantee no reentrance, but for now a safe and effective fix is to take the rtnl_lock in these routines.

If the netdev->features is set with NETIF_F_HIGHDMA, we should set the corresponding netdev->vlan_features as well to allow VLAN netdev created on top of the real netdev to be able to also benefit from HIGHDMA on 32bit system, reducing the performance hit that is caused by __skb_linearize(), particularly for large send. This is fixed in this patch for all Intel e1000, e1000e, igb, ixgbe, and ixgbe drivers since this should be beneficial to all devices supported by these drivers.

Several users report issues with 32-bit adapters when plugged into PCI slots in machines with >= 4GB ram. In particular AMD systems with HyperTransport to PCI bridges seem to trigger the issue, but it isn't limited to only them. This issue is not easily reproducible here, yet still continues to occur in the field. For e1000 on PCI devices, just disable DMA addresses over the 4GB boundary when in PCI (not PCI-X) mode, to prevent the issue from continuing to pop up. The performance impact for this is negligible. The code was refactored to move the init of the hw struct to its own function. This allows the init to be called very early in probe, which then allows using hw-> members for this fix. A slight refactor to the DMA mask code was done for minor correctness based on the instructions in DMA-API-HOWTO.

Based on patches from Sonny Rao and Milton Miller... Combined the patches to fix up clean_tx_irq and clean_rx_irq. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it. The bug can manifest as a data integrity issue (bad payload data) or as a BUG in skb_pull(). This was a nasty bug to hunt down, if people agree with the fix I think it's a candidate for stable. Previously Submitted to e1000-devel only for ixgbe http://marc.info/?l=e1000-devel&m=126593062701537&w=3 We've now seen this problem hit with other device drivers (e1000e mostly) So I'm resubmitting with fixes for other Intel Device Drivers with similar issues.

Back before e1000-7.3.20, the e1000 driver had a simple algorithm that managed interrupt moderation. The driver was updated in 7.3.20 to have the new "adaptive" interrupt moderation but we have customer requests to redeploy the old way as an option. This patch adds the old functionality back. The new functionality can be enabled via module parameter or at runtime via ethtool. Module parameter: (InterruptThrottleRate=4) to use this new moderation method.
