nfp: fix incorrectly set csum flag for nfd3 path

Browse source

The csum flag of IPsec packet are set repeatedly. Therefore, the csum
flag set of IPsec and non-IPsec packet need to be distinguished.

As the ipv6 header does not have a csum field, so l3-csum flag is not
required to be set for ipv6 case.

L4-csum flag include the tcp csum flag and udp csum flag, we shouldn't
set the udp and tcp csum flag at the same time for one packet, should
set l4-csum flag according to the transport layer is tcp or udp.
