Good catch, ntohs() is not necessary, and seems to be there due to an ugly copy-paste error.

Will push a fix for this.

Thanks for reporting

PS: 'H' is for 'H'eader  ;-)

ip6_debug_print prints plen, netxh, hoplim with an extra ntohs, e.g. ntohs(IP6H_PLEN(ip6hdr)), etc - but IP6H_* macros already do ntohs() internally (as hinted by 'H'ost in their names).
