sctp: Use software crc32 checksum when xfrm transform will happen.
[ Upstream commit 27127a82561a2a3ed955ce207048e1b066a80a2a ]
igb/ixgbe have hardware sctp checksum support, when this feature is enabled
and also IPsec is armed to protect sctp traffic, ugly things happened as
xfrm_output checks CHECKSUM_PARTIAL to do checksum operation(sum every thing
up and pack the 16bits result in the checksum field). The result is fail
establishment of sctp communication.
