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.

The igb driver was being incorrectly setup to only allow disabling receive
checksum if multiqueue was disabled. This change corrects that so that
RXCSUM is configured regardless of queue configuration.

We need to support wol on the second port for situations such as when the

This patch adds the support to handle requests from the VF to perform
operations such as completing resets, setting/reading mac address, adding
vlans, adding multicast addresses, setting rlpml, and general
communications between the PF and all VFs.

Add the pf portion of vmdq support. This provides enough support so that
VMDq is enabled, and the pf is functional without enabling vfs.

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.

Both TX and RX hardware time stamping are implemented. Due to
hardware limitations it is not possible to verify reliably which
packet was time stamped when multiple were pending for sending; this
could be solved by only allowing one packet marked for hardware time
stamping into the queue (not implemented yet).
RX time stamping relies on the flag in the packet descriptor which
marks packets that were time stamped. In "all packet" mode this flag
is not set. TODO: also support that mode (even though it'll suffer
from race conditions).

Instead of pulling the mac address from EEPROM it is easier to pull it from
the RAL/RAH registers and then just copy it into the address structures.

This patch removes tx head writeback as it was found to not provide a
significant improvement in tx performance and on some systems has been seen
to cause a performance degredation due to partial cache line writes.

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.
