Hurray!  Thank you!  

This clears the way for most network drivers to be INTR_MPSAFE (ie,
Giant-free).  The only exceptions are drivers like if_bge, if_ti, etc,
which roll their own jumbo frames and use refcounters malloc'ed by
the mbuf subsystem when calling m_extadd() or MEXTADD().  Those are
easy to fix by using pre-allocated ref counters and the ext type
EXT_EXTREF...

Anyway, thanks again.

Drew
