Modified files:
sys/compat/ndis ndis_var.h subr_ndis.c
Log:
MAXPATHLEN is 1024, which means NdisOpenFile() and ndis_find_sym() were
both consuming 1K of stack space. This is unfriendly. Allocate the buffers
off the heap instead. It's a little slower, but these aren't performance
critical routines.
Also, add a spinlock to NdisAllocatePacketPool(), NdisAllocatePacket(),
NdisFreePacketPool() and NdisFreePacket(). The pool is maintained as a
linked list. I don't know for a fact that it can be corrupted, but why
take chances.
