- Use the carp_sx to serialize not only CARP ioctls, but also carp_attach()
and carp_detach().
- Use cif_mtx to lock only access to those the linked list.
- These locking changes allow us to do some memory allocations with M_WAITOK
and also properly call callout_drain() in carp_destroy().
- In carp_attach() assert that ifaddr isn't attached. We always come here
with a pristine address from in[6]_control().

RSS hash from the card. We do not need to hide that under "ifdef RSS" and should
expose that by default so others like lagg(4) can use that and avoid hashing the
traffic by themselves.
While here, improve comments and get rid of hidden/unimplemented RSS support
code for UDP.

--Allow multiple open iic fds by storing addressing state in cdevpriv
--Fix, as much as possible, the baked-in race conditions in the iic
ioctl interface by requesting bus ownership on I2CSTART, releasing it on
I2CSTOP/I2CRSTCARD, and requiring bus ownership by the current cdevpriv
to use the I/O ioctls
--Reduce internal iic buffer size and remove 1K read/write limit by

--Eliminate dynamic allocation in I2CWRITE/I2CREAD
--Move handling of I2CRDWR to separate function and improve error handling
--Add new I2CSADDR ioctl to store address in current cdevpriv so that
I2CSTART is not needed for read(2)/write(2) to work
--Redesign iicbus_request_bus() and iicbus_release_bus():
--iicbus_request_bus() no longer falls through if the bus is already
owned by the requesting device. Multiple threads on the same device may
want exclusive access. Also, iicbus_release_bus() was never
device-recursive anyway.
--Previously, if IICBUS_CALLBACK failed in iicbus_release_bus(), but
the following iicbus_poll() call succeeded, IICBUS_CALLBACK would not be
issued again
--Do not hold iicbus mtx during IICBUS_CALLBACK call. There are
several drivers that may sleep in IICBUS_CALLBACK, if IIC_WAIT is passed.
--Do not loop in iicbus_request_bus if IICBUS_CALLBACK returns
EWOULDBLOCK; instead pass that to the caller so that it can retry if so
desired.

pbufs is a limited resource, and their allocator is not SMP-scalable.
So instead of always allocating pbuf to immediately convert it to bio,
allocate bio just here. If buffer needs kernel mapping, then pbuf is
still allocated, but used only as a source of KVA and storage for a list
of held pages.
On 40-core system doing many 512-byte reads from user level to array of
raw SSDs this change removes huge lock congestion inside pbuf allocator.
It improves peak performance from ~300K to ~1.2M IOPS. On my previous
24-core system this problem also existed, but was less serious.

the index array, not a value for BMCR register. In case of IFM_10_T there
could be either MII_MEDIA_10_T or MII_MEDIA_10_T_FDX, which are 1 and 2,
accordingly. Neither matches a valid BMCR value. My guessing is that this
write is harmless, since later mii_phy_setmedia() would write a proper
value there.
The code is here since the initial checkin. Note that case IFM_100_TX has
the same comment, but a proper value of BMCR_ISO is written. So, collapse
two cases into one, always writing there BMCR_ISO.

building FreeBSD/arm64 VM images and memstick.img installation

r281786:
Add support for building arm64/aarch64 virtual machine images.
r281788:
Copy amd64/make-memstick.sh to arm64/make-memstick.sh for
aarch64 memory stick images.
Although arm64 does not yet have USB support, the memstick
image should be bootable with certain virtualization tools,
such as qemu.
r281792:
Add a buildenv_setup() prototype, intended to be overridden as
needed.
For example, the arm64/aarch64 build needs devel/aarch64-binutils,
so buildenv_setup() in the release.conf for this architecture
handles the installation of the port before buildworld/buildkernel.

A couple of fields are still exposed via struct bpf_if_ext so that
bpf_peers_present() can be inlined into its callers. However, this change
eliminates some type duplication in the resulting CTF container, since
otherwise ctfmerge(1) propagates the duplication through all types that
contain a struct bpf_if.

It is truer to the semantics of logging for messages to *always*
go to the message buffer, where they can eventually be collected
and, in fact, be put into a log file.
This restores the behavior prior to r70239, which seems to have
changed it inadvertently.
