Example #2

/*
 * Given a NIC memory source address and a host memory destination
 *	address, copy 'amount' from NIC to host using shared memory.
 *	The 'amount' is rounded up to a word - okay as long as mbufs
 *		are word sized.  That's what the +1 is below.
 * This routine accesses things as 16 bit quantities.
