 Modified Files:
 	src/sys/dev/pci: if_vioif.c
 
 Log Message:
 simplify vioif_start() - remove the delivery attempts on failure and retries,
 leave that for the dedicated thread
 
 if dma map load fails, retry after m_defrag(), but continue processing
 other queue items regardless
 
 set interface queue length according to the length of virtio queue, so that
 higher layer won't queue more than interface can manage to keep in flight
 
 use the mutexes always, not just with NET_MPSAFE, so they continue
 being exercised and hence working; they also enforce proper IPL level
 
 inspired by discussion around PR kern/52211, thanks to Masanobu SAITOH
 for the m_defrag() idea and code
