I think it allowed to avoid some TX thread wakeups while the socket
buffer is full. But add there another options if ic_check_send_space
is set, which means socket just reported that new space appeared, so
it may have sense to pull more data from ic_to_send for better TX
coalescing.

HW keeps track of RX errors using several counters, each for
specific type of errors. Report RX errors to OS as sum
of all those counters: CRC errors, illegal bytes, checksum,
length, undersize, fragment, oversize and jabber errors.
There is no HW counter for frames with invalid L3/L4 checksums
so add a SW one.
Also add a "rx_errors" sysctl with a copy of netstat IERRORS

There were two definitions for the SCSI VPD Block Device Characteristics (page
0xb1): struct scsi_vpd_block_characteristics and struct
scsi_vpd_block_device_characteristics. The latter is more complete and more
widely used. Convert uses of the former to the latter by tweaking the da driver
and removing sturct scsi_vpd_block_characteristics.
The old code had a O(n) loop, where n is the size of /dev/devstat.
Multiply that by another O(n) loop in devstat_mmap for a total of
O(n^2).
This change adds DIOCGMEDIASIZE support to /dev/devstat so userland can
quickly determine the right amount of memory to map, eliminating the
O(n) loop in userland.
This change decreases the time to run "gstat -bI0.001" with 16,384 md
devices from 29.7s to 4.2s.
Also, fix a memory leak first reported as PR 203097.

During a recent virtual NFSv4 testing event, a bug in the FreeBSD client
was detected when doing I/O DS operations on a Flexible File Layout pNFS
server. For an NFSv3 DS, the Read/Write/Commit nfsstats were incremented
instead of the ReadDS/WriteDS/CommitDS counts.
This patch fixes this.
Only the RPC counts reported by nfsstat(1) were affected by this bug,
the I/O operations were performed correctly.

Instead of running tests one-by-one with the shell wrapper we now run
the full gtest testsuite twice (once as root, once as non root). This
significantly speeds up running tests despite running them twice.
This change also passes the missing -u flag to capsicum-test that caused
test failures (https://bugs.freebsd.org/250178)
Previously, running the testsuite with the wrapper script took ~3s per
test on aarch64 QEMU, i.e. a total of almost 5 minutes.
Now it takes 6 seconds to run all tests twice.
Before:
root@freebsd-aarch64:/usr/tests/sys/capsicum # /usr/bin/time kyua test functional
94/96 passed (2 failed)
309.97 real 58.46 user 244.31 sys
After:
root@freebsd-aarch64:/usr/tests/sys/capsicum # /usr/bin/time kyua test functional
functional:test_root -> passed [2.659s]
functional:test_unprivileged -> passed [2.391s]
2/2 passed (0 failed)
5.48 real 1.06 user 2.52 sys
This overhead is caused by kyua + atf-sh spawning lots of additional
processes and can be avoided by just running the googletest test binary.
