So, obviously, MPTCP can cause problems with Stateful Firewalls (as in asym=
metric routing, out of state packets, etc.). Cisco's take on how to deal w=
ith MPTCP is just as interesting as MPTCP itself is.

Yep, for regular ASAs they advise you to let everything with option 30 set =
in the header have a free pass to your network (turn off NOOP replacement =
of option 30 in TCP headers via a tcp-map)... and btw, turn off packet insp=
ection.
For ASA-X "next generation" firewalls with modern code levels, this behavio=
r seems to be default, although it looks like you can have your packet insp=
ection as well.
