Symptom: After vnicc/rx_bcast has been manually set to 0, bridge_* sysfs parameters can still be set or written. Only occurs on HiperSockets, as OSA doesn't support changing rx_bcast. Vnic characteristics and bridgeport settings are mutually exclusive. rx_bcast defaults to 1, so manually setting it to 0 should disable bridge_* parameters. Instead it makes sense here to check the supported mask. If the card does not support vnicc at all, bridge commands are always allowed.
