- Do not accumulate statistics on every tick.
- Accumulate statistics in vtnet_setup_stat_sysctl()
and in vtnet_get_counter().

reload also if that size was not specified in the new configuration.
Previously it happened only if size was explicitly changed in config.

Using pointer from the cdev directly is dangerous since we have no reference
on it, and it may change any time. That caused panic if device has gone.
While there, report capacity change only if it really changed.

This is primarily only of interest to ZFS developers, but it makes it
easier to get additional debugging.

double-free mbufs.
Like ixgbe(4) chipsets, EOP is only set on the final descriptor
in a chain of descriptors. So, to free the whole list of descriptors,
we should free the current slot _and_ the assembled list of descriptors
that make up the fragment list.
The existing code was setting discard once it saw EOP + an error status;
it then freed all the subsequent descriptors until the next EOP. That's
totally the wrong order.
- Do not ever set a counter to a value. For those counters
that we don't increment, but return directly from hardware
create cases in if_get_counter() method.

If bpobj_space() returned non-zero here, the sublist would have been
left open, along with the bonus buffer hold it requires. This call
does not invoke any calls to bpobj_close() itself.
This bug doesn't have any known vector, but was found on inspection.

imporant moments that we discussed with Marcel and Anuranjan was that
a converted driver should return false for 'grep ifnet if_driver.c' :)

In case if ng_ppp(4) runs only IPv4, with one link, w/o any
encryption and compression, set faster rcvhook method.

Makefiles should not assume that source files can be overwritten. This is the
common case for Perforce source trees.
This is a followup commit to r211243 in the same vein.

This errno value is emitted by dsl_props_set_check() in
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c, and
is used to mean that the property value is too long. For the record,
the maximum length is ZAP_MAXVALUELEN, which is 8*1024 bytes.
Instead of claiming an unknown error (and abort()ing), provide
something more specific to the scenario involved. As far as I
can tell, E2BIG is not emitted for any other scenario.

This change modified the value returned by
dsl_props_set_check(), so that it can distinguish between
a name that's too long and a value that's too long, but
libzfs was not updated accordingly.

This can occur if a spare is being spared, which would yield three
children: the original pool drive, the previous spare, and the spare
that is replacing it.
