dc172872f1 r295133 attempted to deactivate TSO in the 100Mbit link case with this
adapter to work around bugs in TSO handling at this speed.

em_init_locked is called during first boot of the adapter and will
see that link_speed is unitialized, effectively turning off tso for
all cards at all speeds, which I believe was *not* the intent.

Move the handling of TSO deactivation to the link handler where we can
more effectively make the decision about what to do.  In addition,
completely purge the TSO capabilities instead of disabling just CSUM_TSO.

Thanks to jhb for explanation of the hw capabilites api.

Thanks to royger and cognet for testing the 100Mbit failure case to
ensure that their adapters do indeed still work.

6e98c7ae89 Assign a random number to di_gen (for FFS), instead of extracting it
from struct stat.  We don't necessarily have permissions to see the
generation number and the host OS may not have st_gen in struct stat
anyway.  Since the kernel assigns random numbers, there's nothing
meaningful about the generation that requires us to preserve it when
the file system image is created.  With this change, all generation
numbers come from random() and that makes it easier to add support
for reproducible builds at some time in the future (i.e. by adding
an argument to makefs that changes the behaviour of random() so that
it always returns 0 or some predictable sequence).

f2fa1b708a Reduce the bogosity of ministat's % difference calculations.
The previous calculation used an approximation which was only valid in
cases where the means being compared were similar; this resulted in very
odd claims being made, e.g. that 0 +/- 0 is a difference of -100% +/- 1%
from 100 +/- 1.

The new calculation scales sample standard deviations by the means, and
yields approximately correct percentage difference bounds providing that
the reference population is bounded away from zero.  (In the case where
the values being compared are not sufficiently bounded away from zero,
the distribution of ratios becomes much harder to calculate, and is not
likely to be useful anyway.)

Note that when ministat is used for its intended purpose of determining
whether two samples are statistically different, this change is unlikely
to have any noticeable effect; in such cases the means will be similar
enough that the correction applied here will be minimal.

0f62b80bb2 sed(1): add LEGACY_BSDSED_COMPAT compile-time flag.
In r297602, which included a __FreeBSD_version bump to 1100105, we changed
sed 'i' and 'a' from discarding whitespaces to conform with what GNU and
sysvish sed do.

There are arguments in favor of keeping the old behavior but the new
behavior is also useful for migration purposes. It seems important to at
least consider the case of developers depending on the previous behavior,
so add a CFLAG to enable the old behaviour.

1c7bf4098f Do not sleep in vm_wait() if pagedaemon did not yet started. Panic instead.
Requests which cannot be satisfied by allocators at boot time often
have unrealizable parameters.  Waiting for the pagedaemon' start would
hang the boot if done in the thread0 context and just never succeed if
executed from another thread.  In fact, for very early stages, sleep
attempt panics with obscure diagnostic about the scheduler state, and
explicit panic in vm_wait() makes the investigation much shorter by
cut off the examination of the thread and scheduler.

Theoretically, some subsystem might grab a resource to exhaustion, and
free it later in the boot process.  If this unlikely scenario does
appear for real, the way to diagnose the trouble can be revisited.

ffebdbc604 Add a witness check to enforce that no non-sleeping locks are held when

I used this during driver bring-up to find that the Linux driver holds a
whole lot of locks whilst doing their equivalent of busdma operations.

If this works out well, it should be added to the other architecture busdma
implementations to aid in similar debugging.

* bounce buffer and dmar busdma, Lenovo X230 laptop, all the internal
  hardware
* ath(4) too

This is a long time coming.  The general pieces have been floating around
in a local repo since circa 2012 when I dropped the net80211 support

This allows the per-chain RSSI and NF to show up in 'ifconfig wlanX list sta'.
I haven't yet implemented the EVM hookups so that'll show up; that'll come
later.

13d9c12d58 Replace basename(3) by a thread-safe implementation.
Now that the changes to the dirname(3) function had some time to settle,
let's go ahead and use the same approach for replacing basename(3) by a
simple implementation that modifies the input string, thereby making it
thread-safe and guaranteed to succeed.

Unlike dirname(3), this function already had a thread-safe variant
basename_r(3). This function had its own set of problems, like having an
upper bound on the pathname length. Keep this function around for
compatibility, but remove most references from the man page. Make the
man page more similar to that of dirname(3).

As the basename_r(3) function is only provided by FreeBSD (and Bionic),
depending on its use is even more implementation defined than assuming
that basename(3) is thread-safe.

d0dec3458f MFV r308222: 6051 lzc_receive: allow the caller to read the begin record
illumos/illumos-gate@620f322510
620f322510

https://www.illumos.org/issues/6051
  Currently lzc_receive() requires that its snapname argument is a snapshot name
  (contains '@').
  zfs receive allows to specify just a dataset name and would try to deduce the
  snapshot name from the stream.
  I propose to allow lzc_receive() to do the same.
  That seems to be quite easy to implement, it requires only a small amount of
  logic, it does not require any additional system calls or any additional data
  from the stream.
  The benefit is that the new behavior would allow to keep the snapshot names the
  same between the sender and receiver at zero cost, without a need to pass the
  names out of band.
