Although this is not important to the rest of the TCP processing
it is a conveneint way to make the DTrace state-transition probe
catch this important state change.

Most of the EM_* constants are available in all supported host branches,
but EM_AARCH64 was added relatively recently. Add it back to fix

These include standalone X550 adapters, X552 10GbE backplane, and
X552/X557-AT 10GBASE-T; with the latter two being integrated into Xeon D SoCs.

As well, this bumps the ixgbe version number to 2.8.3, and includes updates
to shared code for support for the new devices.

- Use hardware counters for ifnet stats in igb(4) when possible.  This
  ensures these stats include packets that bypass the regular stack via
  netmap.
- Don't derefence values off the end of the igb(4) VF stats structure.
  Instead, add a dedicated if_get_counter method for igb(4) VF interfaces.
- Report missed packets on igb(4) as input queue drops rather than an
  input error.
- Report bug_ring drop counts as output queue drops for igb(4) and ixgbe(4).
- Export the buf_ring drop stats for individual rings via sysctl on
  ixgbe(4).
- Fix a typo that in ixl(4) that caused output queue drops to be reported
  as input queue drops and input queue drops to be unreported.

is harder to maintain and has more overhead.  Modern x86 CPUs include
virtualization extensions that support HVM guests instead of PV guests.
In addition, the PV code was i386 only and not as well maintained recently
as the HVM code.
- Remove the i386-only NATIVE option that was used to disable certain
  components for PV kernels.  These components are now standard as they
  are on amd64.
- Remove !XENHVM bits from PV drivers.
- Remove various shims required for XEN (e.g. PT_UPDATES_FLUSH, LOAD_CR3,
  etc.)
- Remove duplicate copy of <xen/features.h>.
- Remove unused, i386-only xenstored.h.
