Completes on the RCQ of the leading * connection. (Not currently used under FreeBSD until OS support becomes * available.) * * RAMROD_CMD_ID_ETH_HALT * Used when tearing down a connection prior to driver unload. Completes * on the RCQ of the multi-queue/RSS connection being torn down. Don't * use this on the leading connection. * * RAMROD_CMD_ID_ETH_SET_MAC * Sets the Unicast/Broadcast/Multicast used by the port. Completes on * the RCQ of the leading connection. * * RAMROD_CMD_ID_ETH_CFC_DEL * Used when tearing down a conneciton prior to driver unload. Completes * on the RCQ of the leading connection (since the current connection * has been completely removed from controller memory). * * RAMROD_CMD_ID_ETH_PORT_DEL * Used to tear down the leading connection prior to driver unload, * typically fp[0]. Completes as an index increment of the CSTORM on the * default status block. * * RAMROD_CMD_ID_ETH_FORWARD_SETUP * Used for connection offload. Completes on the RCQ of the multi-queue * RSS connection that is being offloaded.
