The amd64 build of boot2 was failing with gcc 6.3.0 due to being more
than 1 kB too large. It was apparently generating a .eh_frame section
which was not being removed by objcopy -S. The .eh_frame section seems
to be mandatory per the amd64 ABI, but boot2 is compiled for i386 (uses
-m32), and therefore should be optional in this context. Suppress
generation of .eh_frame with the -fno-asynchronous-unwind-tables flag to
gcc. This saves 1348 bytes (the limit is 7680 bytes).

The idea here is that, provided upstream pkg(8) maintainers accept
the proposed change, the kernel.ucl will contain a post-install
script causing pkg(8) to emit a message informing to reboot the
system after the kernel is upgraded using 'pkg upgrade', so the
new userland is installed on the running new kernel. At present,
this functionality does not exist in pkg(8), but will help ensure
the upgrade path follows that from UPDATING. To work around this
for now, evaluate ASSUME_ALWAYS_YES, and prompt the user if they
wish to proceed if not set to true.
Since there is a kernel dependency, and a non-GENERIC kernel may
be in use, update Makefile.inc1 to replace '%KERNCONF%' in the
runtime.ucl with the first-built kernel set either via command line
or in make.conf(5).

Some libusb consumers in Linux-land (in this case, libusb4java) expect a
dev_capability member that they can use to enumerate the device

No particular layout is expected of this, just that it can be traversed
using the bLength member until bNumDeviceCapabilities are read and that the

How network VF works with hn(4) on Hyper-V in transparent mode:
- Each network VF has a cooresponding hn(4).
- The network VF and the it's cooresponding hn(4) have the same hardware
address.
- Once the network VF is attached, the cooresponding hn(4) waits several
seconds to make sure that the network VF attach routing completes, then:
o Set the intersection of the network VF's if_capabilities and the
cooresponding hn(4)'s if_capabilities to the cooresponding hn(4)'s
if_capabilities. And adjust the cooresponding hn(4) if_capable and
if_hwassist accordingly. (*)
o Make sure that the cooresponding hn(4)'s TSO parameters meet the
constraints posed by both the network VF and the cooresponding hn(4).
(*)
o The network VF's if_input is overridden. The overriding if_input
changes the input packet's rcvif to the cooreponding hn(4). The
network layers are tricked into thinking that all packets are
neceived by the cooresponding hn(4).
o If the cooresponding hn(4) was brought up, bring up the network VF.
The transmission dispatched to the cooresponding hn(4) are
redispatched to the network VF.
o Bringing down the cooresponding hn(4) also brings down the network
VF.
o All IOCTLs issued to the cooresponding hn(4) are pass-through'ed to
the network VF; the cooresponding hn(4) changes its internal state
if necessary.
o The media status of the cooresponding hn(4) solely relies on the
network VF.
o If there are multicast filters on the cooresponding hn(4), allmulti
will be enabled on the network VF. (**)
- Once the network VF is detached. Undo all damages did to the
cooresponding hn(4) in the above item.
NOTE:
No operation should be issued directly to the network VF, if the
network VF transparent mode is enabled. The network VF transparent mode
can be enabled by setting tunable hw.hn.vf_transparent to 1. The network
VF transparent mode is _not_ enabled by default, as of this commit.
The benefit of the network VF transparent mode is that the network VF
attachment and detachment are transparent to all network layers; e.g. live
migration detaches and reattaches the network VF.
The major drawbacks of the network VF transparent mode:
- The netmap(4) support is lost, even if the VF supports it.
- ALTQ does not work, since if_start method cannot be properly supported.
(*)
These decisions were made so that things will not be messed up too much
during the transition period.
(**)
This does _not_ need to go through the fancy multicast filter management
stuffs like what vlan(4) has, at least currently:
- As of this write, multicast does not work in Azure.
- As of this write, multicast packets go through the cooresponding hn(4).

Before this patch function ofw_bus_find_compatible was using
memory allocations in order to find compatible node and the property's
length. This way there was always a suited buffer for property,
however this approach had also disadvantages - ofw_bus_find_compatible
couldn't be used when malloc is not available, e.g. during fdt fixup stage.
In order to remove the usage limitation of ofw_bus_find_compatible(),
this patch modifies the function to use ofw_bus_node_is_compatible()
(instead of the one without _int suffix), which uses a fixed
buffer on stack instead of dynamic allocations.
