* igb: Record host memory receive overflow in net_statsJesper Dangaard Brouer2009-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | Based on previous patch from Jesper Dangaard Brouer. The RNBC (Receive No Buffers Count) register for the 82576, indicate that frames were received when there were no available buffers in host memory to store those frames (receive descriptor head and tail pointers were equal). The packet is still received by the NIC if there is space in the FIFO on the NIC. As the RNBC value is not a packet drop, the driver stores this value in net_stats.rx_fifo_errors to indicate that there were no system buffers available for the incoming packet. Actual dropped packets are counted in the MPC value. Saving the stats in dev->net_stats makes it visible via /proc/net/dev as "fifo", and thus viewable to ifconfig as "overruns" and 'netstat -i' as "RX-OVR". The Receive No Buffers Count (RNBC) can already be queried by ethtool -S as "rx_no_buffer_count".

* igb: Implement reading of reg RQDPC (Receive Queue Drop Packet Count)Jesper Dangaard Brouer2009-05-26
| | | | | | | | | | | | | | | | | | | | Based on the previous patches from Jesper Dangaard Brouer <hawk@comx.dk> Implement reading the per queue drop stats register RQDPC (Receive Queue Drop Packet Count). It counts the number of packets dropped by a queue due to lack of descriptors available. Notice RQDPC (Receive Queue Drop Packet Count) stats only gets incremented, if the DROP_EN bit it set (in the SRRCTL register for that queue). If DROP_EN bit is NOT set, then the some what equivalent count is stored in RNBC (not per queue basis). The RQDPC register is only 12 bit, thus the precision might suffer due to overrun in-netween the watchdog polling interval.

* igb/igbvf: set rx csum always enabled in hw, disable via swAlexander Duyck2009-05-06
| | | | | | | | | | | | 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 Brandeburg2009-04-28
| | | | | | | | | | | | | | | | | | | | | | 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.

* igb: Replace LRO with GROHerbert Xu2009-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes igb invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. Three things of note: 1) I've kept the LRO Kconfig option until we decide to enable GRO across the board at which point it can also be killed. 2) The poll_controller stuff is broken in igb as it tries to do the same work as the normal poll routine. Since poll_controller can be called in the middle of a poll, this can't be good. I noticed this because poll_controller can invoke the GRO hooks without flushing held GRO packets. However, this should be harmless (assuming the poll_controller bug above doesn't kill you first :) since the next ->poll will clear the backlog. The only time when we'll have a problem is if we're already executing the GRO code on the same ring, but that's no worse than what happens now. 3) I kept the ip_summed check before calling GRO so that we're on par with previous behaviour.

| | | | | | | | | | | | | | When suspending the device the ring structure is freed which causes it to loose track of the count.

* | netdevice: safe convert to netdev_priv() #part-2Wang Chen2008-11-13
|/ | | | | | | | | | | | | | | | | | 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.

* igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok2008-01-28
We are pleased to announce a new Gigabit Ethernet product and its driver to the linux community. This product is the Intel(R) 82575 Gigabit Ethernet adapter family. Physical adapters will be available to the public soon. These adapters come in 2- and 4-port versions (copper PHY) currently. Other variants will be available later. The 82575 chipset supports significantly different features that warrant a new driver. The descriptor format is (just like the ixgbe driver) different. The device can use multiple MSI-X vectors and multiple queues for both send and receive. This allows us to optimize some of the driver code specifically as well compared to the e1000-supported devices. This version of the igb driver no lnger uses fake netdevices and incorporates napi_struct members for each ring to do the multi- queue polling. multi-queue is enabled by default and the driver supports NAPI mode only. All the namespace collisions should be gone in this version too. The register macro's have been condensed to improve readability.
