The format from input for 'tunnel_id' should be network network byte order
And it also should not contain reserved 1 byte, but hardware HASH need the format include reserved 1 byte
And in network byte order. So, this patch convert to that format.
I will add some comment in function ixgbe_fdir_filter_to_atr_input and ixgbe_parse_fdir_filter_tunnel,
That will not Influence other NIC format for this struct member.
Is that ok?
