API should work as following:
- periodicaly report Lower-or-EQual bandwidth (LEQ) connections
over kernel socket, if user application registered for such
per-flow notifications
- report Grater-or-EQual (GEQ) bandwidth as soon as it reaches
specified value in configured time window
Custom implementation of callouts was removed. There is no
point of doing calout-wheel here as generic callouts are
doing exactly the same. The performance is not critical
for such reporting, so the biggest concern should be
to have a code which can be easily maintained.
This is ia preparation for locking rework which is highly inefficient.

The new Mikrotik 10/25G NIC is mostly compatible with AR8151 hardware,
with few exceptions:
* card supports only 32bit DMA operations
* card does not support write-one-to-clear semantics for interrupt status
register
* MDIO operations can take longer to complete
This patch adds support for Mikrotik 10/25G NIC to the alc driver
while maintaining support for all earlier HW.
The patch was tested with FreeBSD main branch as of commit
f4b38c360e
This was tested on Intel i7-4790K system with Mikrotik 10/25G NIC.

The most difficult NFSv4 client recovery case happens when the
lease has expired on the server. For NFSv4.0, the client will
receive a NFSERR_EXPIRED reply from the server to indicate this
has happened.
For NFSv4.1/4.2, most RPCs have a Sequence operation and, as such,
the client will receive a NFSERR_BADSESSION reply when the lease
has expired for these RPCs. The client will then call nfscl_recover()
to handle the NFSERR_BADSESSION reply. However, for the expired lease
case, the first reclaim Open will fail with NFSERR_NOGRACE.
This patch recognizes this case and calls nfscl_expireclient()
to handle the recovery from an expired lease.
This patch only affects NFSv4.1/4.2 mounts when the lease
expires on the server, due to a network partitioning that
exceeds the lease duration or similar.

Pass 1b of fsck_ffs runs only when Pass 1 has found duplicate blocks.
Pass 1 only knows that a block is duplicate when it finds the second
instance of its use. The role of Pass 1b is to find the first use
of all the duplicate blocks. It makes a pass over the cylinder groups
looking for these blocks. When moving to the next cylinder group,
Pass 1b failed to properly calculate the starting inode number for
the cylinder group resulting in the above error message when it
tried to read the first inode in the cylinder group.

On Linux, there's a similar set of programs to ours, but that end in the
letters 'sum'. These act basically like FreeBSD versions run with the -r
option. Add code so that when the program ends in 'sum' you get the
linux -r behavior. This is enough to make most things that use sha*sum
work correctly (the -c / --check options, as well as the long args are
not implemented). When running with the -sum programs, ignore -t instead
of running internal speed tests and make -c an error.

Recent discussion on the nfsv4@ietf.org mailing list confirmed
that an NFSv4 server should reply to an RPC in less than 1second.
If an NFSv4 RPC requires a delegation be recalled,
the server will attempt a CB_RECALL callback.
If the client is not responsive, the RPC reply will be delayed
until the callback times out.
Without this patch, the timeout is set to 4 seconds (set in
ticks, but used as seconds), resulting in the RPC reply taking over 4sec.
This patch redefines the constant as being in milliseconds and it
implements that for a value of 800msec, to ensure the RPC
reply is sent in less than 1second.
This patch only affects mounts from clients when delegations
are enabled on the server and the client is unresponsive to callbacks.

When a module of type "hostuuid" is provided by the loader,
prison0_init strips any trailing whitespace and ASCII control
characters by (a) adjusting the buffer length, and (b) zeroing out
the characters in question, before storing it as the system's
hostuuid.
The buffer length adjustment was correct, but the zeroing overwrote
one byte higher in memory than intended -- in the typical case,
zeroing one byte past the end of the hostuuid buffer. Due to the
layout of buffers passed by the boot loader to the kernel, this will
be the first byte of a subsequent buffer.
This was *probably* harmless; prison0_init runs after preloaded kernel
modules have been linked and after the preloaded /boot/entropy cache
has been processed, so in both cases having the first byte overwritten
will not cause problems. We cannot however rule out the possibility
that other objects which are preloaded by the loader could suffer from
having the first byte overwritten.
Since the zeroing does not in fact serve any purpose, remove it and
trim trailing whitespace and ASCII control characters by adjusting
the buffer length alone.

If the preloaded hostuuid value is invalid and verbose booting is

1. It was missing a trailing \n character.
2. The malformed UUID is printed with %s even though it is not known
to be NUL-terminated.
This commit adds the missing \n and uses %.*s with the (already known)
length of the preloaded UUID to ensure that we don't read past the end
of the buffer.

Currently ipfw has multiple components that are not parts
of GENERIC kernel like dummynet etc. They can bring in important
sysctls if enabled with rc.conf(5) and loaded with ipfw startup script
by means of "required_modules" after initial consult
with /etc/sysctl.conf at boot time. Here is an example of one
increasing limit for dummynet hold queues that defaults to 100:
net.inet.ip.dummynet.pipe_slot_limit=1000
This makes it possible to use ipfw/dummynet rules such as:
ipfw pipe 1 config bw 50Mbit/s queue 1000
Such rule is rejected unless above sysctl is applied.
Another example is a group of net.inet.ip.alias.* sysctls
created after libalias.ko loaded as dependency of ipfw_nat.
This is not a problem if corresponding code compiled in custom kernel
so sysctls exist when sysctl.conf is read early or kernel modules
loaded with a loader. This change makes it work also for GENERIC
and modules loaded by means of rc.conf(5) settings.
