IPv6 fragmentation issue for first fragment

An interesting case is explained here about:


   If a packet is fragmented, the first fragment of the packet (i.e.,
   that with a Fragment Offset of 0) MUST contain the entire IPv6 header

I'm still new to ipv6 and i was thinking about something like this:

if fragoff == 0 && q6->ip6q_unfraglen > 1280, drop_packet(); else process_it();

It's probably wrong, but I'd appreciate some help.

Brightest day,
Blackest night,
No bug shall escape my sight,
And those who worship evil's mind,
be wary of my powers,
puffy lantern's light !
