- Accumulate statistics in vtnet_setup_stat_sysctl()
and in vtnet_get_counter().

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.

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.

The compat counters will go away, but the function will remain in its place,
and in all places where it is going to be called.

- Note the quirk with the interrupt enabled state of the dna handler.
- Use just panic() instead of printf() and panic(). Print tid instead
of pid, the fpu state is per-thread.

with mbufs normally called *m in one place), rename the function
arguments to "mem".
This is a non-functional change.

for amd64/linux32. Fix the entirely bogus (untested) version from
r161310 for i386/linux using the same shared code in compat/linux.
It is unclear to me if we could support more clock mappings but
the current set allows me to successfully run commercial
32bit linux software under linuxolator on amd64.
