>Description:
... which is so '80's :-)

specifically:
```
void
ipsec_hexdump(caddr_t buf, int len)
{
	int i;

	for (i = 0; i < len; i++) {
		if (i != 0 && i % 32 == 0) printf("\n");
		if (i % 4 == 0) printf(" ");
		printf("%02x", (unsigned char)buf[i]);
	}
#if 0
	if (i % 32 != 0) printf("\n");
#endif

	return;
}
```

A way to turn this off would be nice.
