Comment # 14 on bug 8240 from
Ok: I've gone thru the code and fixed a number of bugs.

After looking at the code to do reassembly, I have a question.

It seems to me that fragment_add_seq_next() can be used when reassembling
openvpn carried over udp (the same as for tcp and rather than
fragment_add_seq_check()).

If so, this simplifies the code: no conversation tracking required, etc.

I've tried using fragment_add_seq_next() to reassemble openvpn over udp and it
seems to work OK.

If there's something I've missed which requires the use of
fragment_add_seq_check() when reassembling openvpn over udp please let me know.

If not, I'll commit the code using fragment_add_seq_next() for both.
