I'm not sure it's a good idea to include stepping in the general IP_VER
value because the version and stepping information are used in very
different ways in the driver.
- If we're checking a range of versions, it's an inclusive range of IP
versions that the behavior applies to.
- If we're checking a range of steppings, it's always within one
specific IP version (it's not possible to compare steppings in a
sensible way cross-version) and the comparison is expected to match
an entry in the workaround database. Because the workaround database
is based on "hardware fix" version numbers, the range always has an
exclusive upper bound (since that's the "fix version" at which the
workaround should no longer be applied.
Even if we use CPP trickery to create macros that take default values, I
don't see how we'd use that effectively since the appropriate default
value would change depending on which type of comparison we were doing
(and also whether it was an upper or lower bound for a range).
