So, obviously, MPTCP can cause problems with Stateful Firewalls (as in asymmetric routing, out of state packets, etc.). 
 Cisco's take on how to deal with 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 inspection.

For ASA-X "next generation" firewalls with modern code levels, this behavior seems to be default, although it looks 
like you can have your packet inspection as well.
