Please indicate in the commit message this is backwards compatible with old firmware. I assume it is actually backwards compatible. Andrew --- pw-bot: cr

The latest ICSSG firmware is using different bitmasks and the older bitmasks are no longer compatible with the latets ICSSG firmware. So it is not backwards compatible. I'll mention this in commit message once I post next revision. > Andrew > > --- > pw-bot: cr

The bitmask for EMAC_PORT_DISABLE and EMAC_PORT_FORWARD has been changed in the latest ICSSG firmware. The current bitmasks are wrong and as a result EMAC_PORT_DISABLE and EMAC_PORT_FORWARD commands do not work. Update r30 commands to use the same bitmask as used by the latest ICSSG firmware.
