hpnicfFCoEStaticVfcBindMACAddress holds the MAC address used to bind a static VFC to a specific ENode or remote-FCF; a FIP frame is only associated with this VFC if its source MAC matches this value. Admins set this when the connected device isn't reachable via a single known Ethernet interface, allowing the FCF to match incoming FIP traffic to the right pre-created VFC purely by source MAC. For example, an admin binding a VFC to a remote-FCF reachable across a switched Ethernet fabric would set this to that remote-FCF's known MAC address rather than an ifIndex.
