asks that each buffer be (2048 * 256) bytes long. I suspect that alignment
isn't a real requirement since busdma only recently started honoring it. The
size is also bogus. Fix both of these and stop busdma from trying to
exhaust the system memory pool with bounce pages.

generic bridge support was biting us more than it helped, whenever a new chipset
came out from a vendor and misprogramming it caused strange hangs or corruption.
[2] Add a large number of PCI IDs based on what the linux drivers support.
Note that the new PCI IDs haven't been tested, they're just *likely* to work.
In particular the VIA AGP 8x chipsets are concerning, due to lack of testing,
possible issues (kern/69953), and not having a nice "does this bridge say it
would do 8x" function. However, this shouldn't make the situation worse, since
these chips would have probed in the past anyway.
In contrast to OpenBSD we enable jumbo frame support
depending on MTU setting (like done for xmac).

zero-copy receive of jumbo frames. This eliminates the need for the
jumbo frame allocator implemented in kern/uipc_jumbo.c and sys/jumbo.h.
Remove it.
Note: Zero-copy receive of jumbo frames did not work without these changes;
I believe there was insufficient locking on the jumbo vm object.

the device is suspended or shutting down. This will need to be rethought
slightly if we implement suspend/resume support within vr(4).
This appears to fix the vr_shutdown() panic on SMP machines.
My theory here is there's a race somewhere during vr_detach() with
vr_intr() in the SMP case which was sometimes being triggered,
although quite why this was happening is unclear (vr_stop() also
explicitly disables interrupts by writing to the IMR register).

MAC address stored in the "local-mac-address" property of the device's
OFW node if present and the host address/system default MAC address if
the node doesn't doesn't have such a property. If set to "false" the
host address will be returned for all devices like before this change.
This brings the behaviour of device drivers for NICs with OFW support/
