| | | | | | | | | | | | | | | | | | | | | | The setup_rctl call was making a call into the ring structure after it had been freed. This was causing a panic on shutdown. This call wasn't necessary since it is possible to get the needed index from adapter->vfs_allocated_count.

* | e1000/e1000e/igb/ixgb: don't txhang after link downJesse Brandeburg2009-05-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | after the recent changes to wired drivers to use only netif_carrier_off the driver can have outstanding tx work to complete that will never complete once link is down. Since the intel hardware will hold this tx work forever, the driver notices a tx timeout condition internally and might try to instigate printk and reset of the part with a netif_stop_queue, which doesn't work because link is down. Don't bother arming to tx hang detection when link is down.

* | igb/igbvf: set rx csum always enabled in hw, disable via swAlexander Duyck2009-05-073-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | An issue was found in which rx checksum could not be enabled without resetting the interface. The issue was the hardware enable was not being done via ethtool. To resolve this issue and prevent conflicts with VF configuration we will leave the feature always enabled in hardware, and then in software we will choose to ignore the results via a sw flag.

* | igb: Enable SCTP checksum offloadingJesse Brandeburg2009-04-284-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally from: Vlad Yasevich <vladislav.yasevich@hp.com> This patch, both the driver portion and the sctp code was modified by Jesse Brandeburg and is Copyright(c) 2009 Intel Corporation. Thanks go to Vlad for starting this work. Intel 82576 chipset supports SCTP checksum offloading. This patch enables this functionality in the driver. A new NETIF feature is introduced for SCTP checksum offload. If the driver supports CRC32c checksum, it can set this feature flag. The hardware can offload both transmit and receive.

| | | | | | | | | | | | | | | | | | | | | | | | Both of these drivers do a check to verify ip_summed is set to CHECKSUM_UNNECESSARY prior to passing the packet to GRO.

|/ | | | | | | | | | | | | | | | | | | | As reported by Andrew Lutomirski <amluto@gmail.com> All the intel wired ethernet drivers were calling netif_carrier_off and netif_stop_queue (or variants) before calling register_netdevice This is incorrect behavior as was pointed out by davem, and causes ifconfig and friends to report a strange state before first link after the driver was loaded, since without a netif_carrier_off, the stack assumes carrier_on, but before register_netdev, netlink messages are not sent out telling link state. This apparently confused *some* versions of networkmanager.

To prevent VFs from loading automatically a module parameter "max_vfs" was added so that the number of VFs per PF can be limited. This is especially useful when 4 or more 82576 ports are on the system because otherwise to load all VFs would result in 8 interface per physical port.

| | | | | | | | | | | | | | | | | | | | Impact: Fix Yinghai Lu found one system with 82575EB where, in the kernel that is kexeced, probe igb failed with -2, the reason being that the adapter could not be brought back from D3 by the kexec kernel, most probably due to quirky hardware (it looks like the same behavior happened on forcedeth). Prevent igb from putting the adapter into D3 during shutdown except when we going to power off the system. For this purpose, seperate igb_shutdown() from igb_suspend() and use the appropriate PCI PM callbacks in both of them. Signed-off-by: "Rafael J.

As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface.

* | igb: transition driver to only using advanced descriptorsAlexander Duyck2009-02-164-166/+32
| | | | | | | | | | | | | | | | | | | | | | | | Currently the driver uses advanced descriptors for its main functionality, but then uses legacy when testing. This patch changes this so that advanced descriptors are used throughout and all mentions of legacy descriptors are removed.

* | igb: remove unused definesAlexander Duyck2009-02-168-175/+11
| | | | | | | | | | | | | | | | | | | | This patch removes all of the unused defines from the .h files contained in igb. For some defines there was a use and so I plugged them into the correct locations.

* | igb: cleanup incorrect comment and set IP Checksum EnableAlexander Duyck2009-02-161-10/+4
| | | | | | | | | | | | | | | | | | | | | | IP Checksum enable doesn't need packet split in order to function. It only requires the use of advanced descriptors which the current igb driver does. So we can enable it always without any issues.
