net/mlx4_en: Fix endianness bug in IPV6 csum calculation
[ Upstream commit 82d69203df634b4dfa765c94f60ce9482bcc44d6 ]
Use htons instead of unconditionally byte swapping nexthdr. On a little
endian systems shifting the byte is correct behavior, but it results in
incorrect csums on big endian architectures.
Fixes: f8c6455bb04b ('net/mlx4_en: Extend checksum offloading by CHECKSUM COMPLETE')
