igb: Enable SCTP checksum offloading
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.
