I sure can.
This function returns IPSEC_HDR_DONT_PROCESS when there is a destination
IPv6 options bag. This is because you could get a situation like this:
IP + destopts + routing-hdr <not-fully-transited> + AH + <data>
and that situation was often described as the "Mobile IPv6 situation" because
apparently there was some Mobile IPv6 destination option that would've been
conducive to the above situation.
Feel free to change the comment to remove Mobile IPv6 from it. Hmmm... how
'bout this :
/*
* Return DONT_PROCESS because the destination options header may
* be for each hop in a routing-header, and we only want AH if we're
* finished with routing headers.
*/
That's more accurate AND it removes "Mobile IPv6" from the text.
