History
gallatin 53ffe07705 o Introduce a new external mbuf type, EXT_EXTREF. 
o Allow callers of m_extadd() to allocate their own reference
m_ext.ref_cnt pointer, rather than having the mbuf system allocate it
with a malloc() in the critical path.  This speeds m_extadd() up, and
also simplifies locking (malloc() may need Giant).

A driver or subsystem wishing to take use its own ref counter must
initialize m_ext.ref_cnt to point to its ref counter prior to
calling m_extadd(), and it must use EXT_EXTREF as its external type.

Eg:
	 m->m_ext.ref_cnt =  my_ref_cnt_ptr;
	 m_extadd(.....,EXT_EXTREF);
