Hi Angela,
Support list and check list are the two dimensions for check whether cases can run on current validation environment. 

If you've known that only one or two kinds of NIC supported by some cases, you can add it into support list.
When case name matched in support list, NIC/OS/Target will be checked in sequence. If any of them not matched, case will be skipped.
If you've known that one case can't run in certain environment like i686 or NIC, you can add it into check list.
When case name matched in check list, NIC/OS/Target will be checked in sequence. If any of them matched, case will be skipped.

These information is tracked by excel for it need to be readable. Binary patch is hard to read, so commit log should mention what has been changed.
Other format like Json/XML should be better choice. Currently, we have on plan on that.

For long term, we will add suite based configuration file and in that file we can track some special things like fm10k not support SCTP checksum.
