On UFS with SU+J, sometimes fsck's default recovery from journal marks the
filesystem as clean but some errors remain.
With SU only, default fsck in preen mode sometimes thinks all errors have
been fixed but some still remain.
To address the issues above, this change adds a new config option:
fsck_flags. By default it's set to -p, but the user may change it to -y
or -f -y, for instance, to force a full fsck after a system crash.

When I implemented MD DYNAMIC parsing, I was originally passing a
linker_file_t so that the MD code could relocate pointers.
However, it turns out this isn't even filled in until later, so it was
always 0.
Just pass the load base (ef->address) directly, as that's really the only
thing we were interested in in the first place.
This fixes a crash on RB800 where it was trying to write to an unmapped

It turns out that units(1) is not as horrible to use in scripts
as I initially thought. When the --terse flag is combined
with an appropriate output format (set via --output-format),
units(1) is actually capable of producing very nice results.
For example:
units -o %0.f -t '4 gigabytes' bytes
is is just going to print out the expected value of 4294967296.
There is no time to waste. People have to know about it.
I am adding an example for this at the top of the examples section
because this is what users are most likely looking for.

required that constraint. It turns out that some of the
implementations still do, and on such systems, the device will fail to

The intent seems to be zeroing all of the cc_cpu array, or its singleton on
such platforms. The assumption made is that the BSP is always zero. The
code smell was introduced in r326218, which changed the prior explicit zero
to 'curcpu'. The change is only valid if curcpu continues to be zero,
contrary to the aim expressed in that commit message.
So, more succinctly, the expression could be: memset(cc_cpu,0,sizeof(cc_cpu)).
However, there's no point. cc_cpu lives in the data section and has a zero
initial value already. So this revision just removes the problematic
statement.
No functional change. Appeases a (false positive, ish) Coverity CID.

These adjustments improve performance with jumbo frames and/or LRO
enabled (i.e., when there may be multiple descriptors per packet) by
increasing the default size of the receive queues and by always using
page-sized buffers for the body type receive ring.
This patch also adjust the initialization of the max frame size to
remove cases where certain configuration sequences would result in 2K
receive buffers being used instead of 4K ones when jumbo frames were
enabled.

This fixes a bug where the checksum offload status of received packets
was being taken from the first descriptor instead of the last, which
affected LRO packets.
The driver has been hardened against the device skipping receive
descriptors, although it is not believed that this can occur given the
way this implementation configures the receive rings.
Additionally, for packets received with the error indicator set, the
driver now forces the length of all fragments in that packet to zero
prior to passing it to iflib. Such packets should wind up being
discarded at some point in the stack anyway, but this removes any
questions by killing them in the driver.
Counters have been added (and exposed via sysctls) for skipped receive
descriptors, zero-length packets received, and packets received with
the error indicator set so that these conditions can be easily
observed in the field.
