lsm-pf.so is an example that uses the pfil interface.

There's currently no way to pass an mbuf out of
the stack.  If pfil is used in a stack module
an mbuf can be manipulated directly.

If by "application" you mean a process outside of io-pkt
then the pfil interface can't be used.  If you want to
pass packet data outside of the stack take a look at BPF /
libpcap.
