Discussion

Indicates that the TCP or UDP checksum was calculated. The value for the checksum calculated in hardware should be passed as the second parameter of mbuf_set_csum_performed. The hardware calculated checksum value can be retrieved using the second parameter passed to mbuf_get_csum_performed. This should be done for IPv4 or IPv6.
