ixgbe: should not use HW_CSUM, should use IP* flags
as mentioned by Herbert, our hardware supports IP offloads, not full checksum offloads for any protocol in existence (even though the hardware just provides generic csum support over any range of bytes) Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
