It calls OF_* functions to check if it needs to implement workarounds.
This may not be the case on arm64 where we support both FDT and ACPI.
Fix this by checking if we are booting on FDT before calling these checks.

Chain frames required to satisfy all 2K of declared I/Os of 128KB each take
more then a megabyte of a physical memory, all of which existing code tries
allocate as physically contiguous. This patch removes that physical
contiguousness requirement, leaving only virtual contiguousness. I was
thinking about other ways of allocation, but the less granular allocation
becomes, the bigger is the overhead and/or complexity, reaching about 100%
overhead if allocate each frame separately.
The patch also bumps the chain frames hard limit from 2K to 16K. It is more
than enough for the case of default REQ_FRAMES and MAXPHYS (the drivers will
allocate less than that automatically), while in case of increased MAXPHYS
it will control maximal memory usage.

After the auth key is copied into the ipad[] array, any remaining bytes
are cleared to zero (in case the key is shorter than one block size).
The full block size was used as the length of the zero rather than the
size of the remaining ipad[]. In practice this overflow was harmless as
it could only clear bytes in the following opad[] array which is
initialized with a copy of ipad[] in the next statement.

Now that we're queueing BIO_DELETE requests in the CAM I/O scheduler,
it make sense to try to combine as many as possible into a single
request to send down to hardware. Hopefully, lots of larger requests
like this are better than lots of individual transactions.
Note for future: need to limit based on total size of the trim
request. Should also collapse adjacent ranges where possible to
increase the size of the max payload.

Trying to grab locks during cngrab() when entering the debugger is
deadlock prone as all other CPUs are already halted (and thus unable
to release locks) when cngrab() is invoked. One could instead use
try-locks. However, the case that the try-lock fails still has to
be handled. In addition, if the try-lock works it doesn't provide
any greater ordering guarantees than is already provided by entering
and exiting DDB. It is simpler to define a simpler path for the
case that the try-lock would fail and always use that when entering
DDB. Messing with timers, etc. when entering DDB is dubious even if
the try-lock succeeds.
This patch attempts to use the smallest possible set of operations to
grab the vt(4) console when entering DDB without using any locks.

associated with the wait, use curthread' policy domainset. The

the new helper vm_wait_doms(), which directly takes the bitmask of the
domains to wait for passing min condition.

Eliminate VM_WAIT and VM_WAITPFAULT macros, the direct functions calls

renames gpio_pin_get_by_ofw_impl() to gpio_pin_get_by_ofw_propidx() and
provides a declaration for it in a public header.
Previously there were functions to get a pin by property name (assuming
there would only be one pin defined for the name), or by index (asuming
the property has the standard name "gpios"). It turns out there are
devicetree bindings that describe properties with names other than "gpios"
which can describe multiple pins. Hence the need to retrieve the Nth item
from a named property.

decide themselves if they want to use DRIVER_MODULE or EARLY_DRIVER_MODULE

Mainly, this adds extern declarations for the driver and devclass variables.
It also renames ofwiicbus_devclass to ofw_iicbus_devclass to be consistant
with the way we use ofw_ prefixes on this stuff.

Panasas discovered that ioctl(SIOCGLAGGPORT) returns ENOTTY for mxge(4) when
the NIC is not a member of a lagg. This came as a surprise, because the
SIOCGLAGGPORT handler in if_lagg.c only returns ENOENT (if run against the
laggX interface, rather than a physical port) or EINVAL (if run against a
non-member physical port). This behavior was not seen with other drivers,
such as bge(4), igb(4), and cxl(4). When I compared their respective ioctl
handlers, I found that they all called ether_ioctl() for the default (i.e.
unhandled) case; by contrast, mxge(4) only calls ether_ioctl() for two
specific cases, and returns ENOTTY for the default case.
Remove the two cases which explicitly call ether_ioctl(), and let the
default case call it instead. This matches what the vast majority of the NIC
drivers do.
