Yes. Especially if you use RF23x devices that drop packets. If you are
working on fragmentation take a look at it and see how hard it is to
add.

PPP/SLIP are adding an unnecessary layer of complexity. For example
I'm not sure yet if they work right for IPv6.  It also makes routing
more complex. Now the 802.15.4 LAN is hooked to the Ethernet LAN by a
PTP link instead of a direct connection. Broadcast packets are not
normally forwarded over PTP links so radvd is messed up. All of this
is making me learn a lot more about IPv6 than I wanted to.
