What is swMSTPInstInternalRootCost?

This read-only value reports the path cost to the Regional Root for this instance: to the CIST Regional Root for the CIST, or to the MSTI Regional Root for an MSTI. Admins use this to see how far, in cost terms, this bridge is from the root within its own MST Region.
