[dts] [PATCH] /tests/TestSuite_nvgre : add ipv6 detect and ipv6checksum for CVL25gand100g nic Add ipv6 detect case and ipv6 checksum offload case for the CVL 25g and 100g nic test Add CVL25G and 100g nic support default none vector

[Lin, Xueqin]

Patch title is too long, you could put some explanation in the comment. 
Some comment as below. 

Best regards,
Xueqin

[xueqin] have defined self.inner_ip6_src, self.inner_ipv6_dst, self.outer_ipv6_src, self.outer_ipv6_dst above, why repeat to add ipv6 src, dst... similar code here? 
Are you sure code could be called? Pls check create_pcap() code.

[xueqin] if run no nvgre packet, should only set outer_ip_proto=0xFF.
outer_l3_type = "IPv6", inner_l3_type="IPv6  are for nvgre packet.

> +        # check nvgre + IP inner packet

[xueqin] below is ipv6 inner packet.

[xueqin] below is tcp inner packet

[xueqin] same as above.

[xueqin] inner ipv6.
