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.
