This is part of an ongoing cycle of commits on all the BSDs to
merge the USB vendor and device defintions..
A merge from OpenBSD is still pending.

multiple IRQs (which is nonsense for _CRS) when the link hasn't been
programmed. Before, this was a KASSERT. A ServerWorks system was
seen returning IRQs of 0, 2 in response to _CRS before link setup.
Thanks to sam@ for quick testing and turnaround on this.

datasheet says it is only valid for such chipsets and shouldn't be used
with others. This fixes some 82559 based cards which otherwise only
work at 10Mbit.

In contrast to OpenBSD we enable jumbo frame support
depending on MTU setting (like done for xmac).

Keeping consumers open when device is closed is very hard. We need to
open consumers sometimes to update metadata, etc.
Many hacks was introduced in the past to made it possible. You cannot
be sure that you can open consumer for writing always, even if you think
it should be allowed. If one of the mirror components is for example da0
and you try to open it, you can get EPERM when da0s1 is opened for reading
(because BSD class opens consumers (da0) with an extra 'e' bit set).
Waiting for the events queue to be empty may do the trick, but it makes
code much uglier (as you cannot always call g_waitidle()), it doesn't
solve all edge cases and it can introduce deadlocks if there are events
in the queue that wait for gmirror.
I removed those hacks. Now all consumers are open r1w1e1 always, even if
device is closed. Maybe it is less clean from GEOM perspective, but simpify
code a lot and make it much more reliable.
The only issue was retaste event which is sent when we close consumers
opened for writing. I ignore retaste event by not detaching consumer
immediately (so retaste event is not send to my class) and sending event
right after it to detach and destroy consumer.
prevents a possible endless loop in pf_get_sport() with 'static-port'
ICMP state entries use the ICMP ID as port for the unique state key. When
checking for a usable key, construct the key in the same way. Otherwise,
a colliding key might be missed or a state insertion might be refused even
though it could be inserted. The second case triggers the endless loop,
possibly allowing a NATed LAN client to lock up the kernel.

- Implement arm_mask_irqs and arm_unmask_irqs
- Provide the available physical address range after pmap_bootstrap allocated
things, instead or before, or bad things happen.
call mmap() to create a shared space, and then initialize umtx on it,
after that, each thread in different processes can use the umtx same
as threads in same process.
2. introduce a new syscall _umtx_op to support timed lock and condition
variable semantics. also, orignal umtx_lock and umtx_unlock inline
functions now are reimplemented by using _umtx_op, the _umtx_op can
use arbitrary id not just a thread id.
there is some hope for the 32-bit management utilities to run. I've used
the cli successfully, but 3dm2 doesn't work for other reasons. Of course,
a native binary of the 3dm2 and cli would be much better, but that doesn't
exist.
o don't encapsulate on tx; the chip expect a raw frame w/o the crypto header
o clear the WEP bit in the 802.11 header on rx so the 802.11 layer doesn't
try to strip the crypto header
o clobber the "drop unencoded frames" state bit when privacy is enabled so
rx'd frames we pass up to the 802.11 layer are not discarded as unencrypted
This stuff will need to be redone if anyone decides to add WPA support.

for no good reason). The new format of sillyrenames looks like
