introduction: document bitfield notation
Bitfields are a useful and familiar way to specify sub-byte structure layout. The only issue is that bitfield order isn't portable across architectures. Document that we list bitfields from least to most significant one, and warn about portability issues. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Approved-by: https://www.oasis-open.org/apps/org/workgroup/virtio/ballot.php?id=3177 Fixes: https://github.com/oasis-tcs/virtio-spec/issues/3
