 Committed By:	jdolecek

 Modified Files:
 	src/sys/kern: kern_pmf.c
 Log Message:
 need to take IFNET_LOCK() around if_stop (on suspend) and if_init (on resume)
 calls, those need to read and/or manipulate if_flags and hence need
 the lock for IFEF_MPSAFE drivers; the drivers can't do IFNET_LOCK() themselves,
 because the ioctl path call these hooks with the lock held
