description:
Summary: Disable ixg(4) until the linuxist mb() API re-definition
within the XEN amd64 dom0 build is resolved.

Detail:
The xen public headers >= 0x00030201 depend on a linuxism - a memory
barrier "API" namely mb(), rmb() and wmb(). These are made accessible
to NetBSD code via the interface
sys/external/bsd/common/include/asm/barrier.h

Currently the ixg(4) driver uses an identical API by defining them
(incorrectly) to inline assembler macro definitions in
sys/dev/pci/ixgbe/ixgbe_osdep.h

This will result in the dom0 builds failing to build due to this
redefinition of the macros. We therefore disable the driver in
NetBSD/amd64 dom0 in order to facilitate smoothly moving the XEN
kernel builds to the new XEN source level API (RELEASE-4.11.1).

The fix for this is trivial, but needs the attention of the driver
maintainer.
