specific parameter.
Tape drives include write protect (WP), Buffered Mode and Speed
settings in the device-specific parameter. Clearing this
parameter on a mode select can have the effect of turning off
write protect or buffered mode, or changing the speed setting of
the tape drive.
Disks report DPO/FUA support via the device specific parameter
for MODE SENSE, but the bit is reserved for MODE SELECT. So we
clear this for disks (and other non-tape devices) to avoid
potential errors from the target device.

the TOE. For now this capability is always enabled in kernels with
options RATELIMIT. t4_tom will check if_capenable once the base driver
gets code to support rate limiting for any socket (TOE or not).
This was tested with iperf3 and netperf ToT as they already support
SO_MAX_PACING_RATE sockopt. There is a bug in firmwares prior to
1.16.45.0 that affects the BSD driver only and results in rate-limiting
at an incorrect rate. This will resolve by itself as soon as 1.16.45.0
or later firmware shows up in the driver.

This will help application developers simulate end of tape conditions.
To inject an error in sa0:
sysctl kern.cam.sa.0.inject_eom=1
This will return the next read or write request queued with 0 bytes
written. Any subsequent writes or reads will go along as usual.
This will also cause the early warning position flag to get set
for the next position query. So, 'mt status' will show the BPEW
(Beyond Programmable Early Warning) flag on the first query after
an error injection. After that, the position flags will be as they
are in the underlying tape drive.
Also, update the sa(4) man page to describe tape parameters,
which can be set via 'mt param'.
sys/cam/scsi/scsi_sa.c:
In saregister(), create the inject_eom sysctl variable.
In sastart(), check to see whether inject_eom is set. If
so, return the read or write with 0 bytes written to
indicate EOM. Set the set_pews_status flag so that we
fake PEWS status in the next position call for reads, and the
next 3 calls for writes. This allows the user to see the BPEW
flag one time via 'mt status'.
In sagetpos(), check the set_pews_status flag and fake
PEWS status and decrement the counter if it is set.
share/man/man4/sa.4:
Document the inject_eom sysctl variable.
Document all of the parameters currently supported via
'mt param'.

Refactoring done in r317703 broke -c, -l, and -L flags implying
suppression of match printing. Fortunately this is just a matter of not
doing any printing of the resulting matches and context printing was not
broken in this refactoring.
Add some regression tests since this area may still see further
refactoring, include different context flags as well even though they
were not broken in this case.

makefs(1) has a number of signedness warnings (when built with higher

in makefs itself.
There is one case where a signedness warning arises from the blksize
macro, so must be addressed in the macro itself.
