chipset. The MAC address is stored in the APC CMOS RAM and we have to
commit trememdous evil in order to read it. The code to do this is only
activated on the i386 platform. Thanks to Cameron Grant for providing
access to a test box for me to tinker with.
This will fix the problem where the sis driver ends up with a station
address of 00:00:00:00:00:00 on boards that use the 630E chipset.
* a ">" is really ">=" ;
* do not try to fetch zero-sized blocks from the card;
* make sure that bpf gets the packets it wants even with
bridging active;
different hardware address, we should drop it (this should only
happen in promiscuous mode). Relocate the code for this check
from before ng_ether(4) processing to after ng_ether(4) processing.
Also fix a compiler warning.

kmem_free() for now. Kmem_malloc() and kmem_free() now have appropriate
assertions in place, and these checks aren't feasible until more of the
networking code is locked down. Also, the extra assertions here should
already be caught by the WITNESS code as lock order violations should
mutex operations on Giant be reintroduced here later.
adv_free() as the ISA probe routine doesn't malloc() ccb_infos but does
call adv_free().
- Release the ISA-only overrun DMA tags, bufs, and maps if the probe fails.

the index of the pollfd array to the number of fd's currently open, not
the maximum number of fd's. ie: if you had 0,1,2 open, you could not
use pollfd slots higher than 20. The specs say we only have to support
OPEN_MAX [64] entries but we allow way more than that.
only covers about 3-4 lines.
- Don't lower the IPL while we are on the interrupt stack. Instead, save
the raised IPL and change the saved IPL in sched_lock to IPL_0 before
calling mi_switch(). When we are resumed, restore the saved IPL in
sched_lock to the saved raised IPL so that when we release sched_lock
we won't lower the IPL. Without this, we would get nested interrupts
that would overflow the kernel stack.

also try implement teh documented behaviour in socket nodes
so that when there is only one hook, an unaddressed write/send
will DTRT and send the data to that hook.
