[RJ] In IETF98, Pascal had presented the problem stmts related to 6lo
fragmentation and post-session there was a discussion (
Also my experience with regards to 6lo frag also points to problems similar
to what were mentioned during that session.

[RJ] i think i didnt appropriately word my stmts. I never suggested to not
support or disable 6lo fragmentation. In my experiment i have disabled it
just to check if there are any reasons why RIOT should result in 6lo
fragmentation. I found this (DAO) case and thought, may be, this is not a
good candidate to result in 6lo frag and can be avoided and hence the mail.
