P-state but not C-state invariant TSC by changing the default behavior
to leaving the TSC enabled as the timecounter and disabling C2+ instead
of disabling the TSC by default.

Add separate software Tx queue limit for non-TCP traffic to make total
limit higher and avoid local drops of TCP packets because of no
backpressure.
There is no point to make non-TCP limit high since without backpressure
UDP stream easily overflows any sensible limit.
Split early drops statistics since it is better to have separate counter
for each drop reason to make it unabmiguous.
Add software Tx queue high watermark. The information is very useful to
understand how big queues grow under traffic load.

Most likely is was just memory leak on the error handling path since
typically efsys_mem_t is filled in by zeros on allocation.

sfxge_dma_alloc() calls bus_dmamem_alloc() with BUS_DMA_ZERO flag, so
allocated memory is already filled in by zeros

Remove the first member alignment to cacheline since it is nop.
Use __aligned() for the whole structure to make sure that the structure
size is cacheline aligned.
Remove lock alignment to make the structure smaller and fit all members
used on event queue processing into one cacheline (128 bytes) on x86-64.
The lock is obtained as well from different context when event queue
statistics are retrived from sysctl context, but it is infrequent.
Reorder members to avoid padding and go in usage order on event
processing.
As the result all structure members used on event queue processing fit
into exactly one cacheline (128 byte) now.

In fact the pointer is used only if more than one TXQ is processed in
one interrupt.
It is used (read-write) on completion path only.
Also it makes the first part of the structure smaller and it fits now
into one 128byte cache line. So, TXQ structure becomes 128 bytes smaller.

string.
With this change it is not necessary redeclare the driver relations with
gpiobus and gpioc.
This also prevents redundant declarations when gpiobusvar.h is included
(which is going to happen soon).
It seems GAS makes the substitution automatically, but Clang's
integrated assembler does not (yet). It fails with "invalid operand for
instruction."

In all cases, the file field of struct radius is a char array, but the
intent was to check whether the string is empty, so add an indirection
to achieve that. Use a similar approach for the sockname field of

Strip is often used to modify existing files, rather than creating new
files. If the existing file has hard links or is a symbolic link, act as
if editing the file in place and preserve the links.

Replace 'system' with 'release' in CLEANFILES, and add
'disc1' to CLEANDIRS.
Ensure the 'dvd' target depends on 'packagesystem'.
Fix 'mini-memstick.img' prerequisite, which should be the
'bootonly' target, not 'disc1' (previously 'system').
Use .TARGET as the target installation directory for the
disc1.iso and bootonly.iso images, which now expand to
'disc1' and 'bootonly' respectively, mimicking the behavior
of the 'dvd' target.
Remove '@true' from the 'release' target, and instead use
'touch ${.TARGET}' to prevent multiple iterations of
'make release' from clobbering previously-built installer

to UFS, perform updates during syncer scans, which in particular means
that tmpfs now performs scan on sync. Also, this means that a mtime
update may be delayed up to 30 seconds after the write.
The vm_object' OBJ_TMPFS_DIRTY flag for tmpfs swap object is similar
to the OBJ_MIGHTBEDIRTY flag for the vnode object, it indicates that
object could have been dirtied. Adapt fast page fault handler and
vm_object_set_writeable_dirty() to handle OBJ_TMPFS_NODE same as
OBJT_VNODE.
