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.
