try re-ordering the member variables in the initialiser. the order of
class declaration (in mip.h) should match the order of initialisation 
(in mip.cc)

that is odd since off_ip_ being a protected variable of class instance
MIPDecapsulator, should be accessible by the instance methods such as the
recv() function. well, you could try to use the hdr macro used all over ns
:

hdr_ip *pouthdr = HDR_IP(p) ;// defined in packet.h

instead of 
hdr_ip *pouthdr = (hdr_ip*)p->access(off_ip_); 

and get rid of off_ip_. you could do the same with all offsets.

hope this helps,
