Changes to viona and bhyve are generally additive, and backwards-compatible. Checking that the header API version definitions match those in Propolis is more restrictive than we are at runtime; generally beeing *newer* than the OS interface is OK, while *older* is not. If viona or bhyve changes are not backwards-compatible, header-check will still report them as applicable to items that Propolis has definitions of too. If changes simply remove items some twiddling with the header-check/build.rs rules may be in order, so that Propolis checked against older API versions can know that items which were once present are no longer.

5ffff4b(nice hash!) stlouis has had aVIONA_CURRENT_INTERFACE_VERSIONof 7, which differs from the existing minimum Propolis requires of 6. the last time this was changed was back when we added multi-queue support to viona, which predates me adding header-check as part of CI (... as a result of a bug that came in with that change!) ... when the CI illumos was updated in the last few weeks, the value we see in header-check finally got the update too. as-is, because the constant doesn't match between our definition and the kernel headers,header-checkhandles that as any other constant mismatch and fails CI. in any other case this would be right, such as if ioctl values were curiously changing around beneath our feet.. but here it's generally ok.while viona's header-check now supports a notion of
API_VERSION, I don't know of any items which have been removed and I don't want to add conflicts for new versions. so I'm adding it in here really in service of future use (perhaps in #1093?)this gets CI green again, which really had no need to be failing. sorry for the troubles @zeeshanlakhani
