888  *
889  * A slowpath command is used to propogate a configuration change through
890  * the controller in a controlled manner, allowing each STORM processor and
891  * other H/W blocks to phase in the change.  The commands sent on the
892  * slowpath are referred to as ramrods.  Depending on the ramrod used the
893  * completion of the ramrod will occur in different ways.  Here's a
894  * breakdown of ramrods and how they complete:
895  *
896  * RAMROD_CMD_ID_ETH_PORT_SETUP
897  *   Used to setup the leading connection on a port.  Completes on the
898  *   Receive Completion Queue (RCQ) of that port (typically fp[0]).
899  *
900  * RAMROD_CMD_ID_ETH_CLIENT_SETUP
901  *   Used to setup an additional connection on a port.  Completes on the
902  *   RCQ of the multi-queue/RSS connection being initialized.
903  *
904  * RAMROD_CMD_ID_ETH_STAT_QUERY
905  *   Used to force the storm processors to update the statistics database
906  *   in host memory.  This ramrod is send on the leading connection CID and
907  *   completes as an index increment of the CSTORM on the default status
908  *   block.
909  *
910  * RAMROD_CMD_ID_ETH_UPDATE
911  *   Used to update the state of the leading connection, usually to udpate
912  *   the RSS indirection table.  Completes on the RCQ of the leading
913  *   connection. (Not currently used under FreeBSD until OS support becomes
914  *   available.)
915  *
916  * RAMROD_CMD_ID_ETH_HALT
917  *   Used when tearing down a connection prior to driver unload.  Completes
918  *   on the RCQ of the multi-queue/RSS connection being torn down.  Don't
919  *   use this on the leading connection.
920  *
921  * RAMROD_CMD_ID_ETH_SET_MAC
922  *   Sets the Unicast/Broadcast/Multicast used by the port.  Completes on
923  *   the RCQ of the leading connection.
924  *
925  * RAMROD_CMD_ID_ETH_CFC_DEL
926  *   Used when tearing down a conneciton prior to driver unload.  Completes
927  *   on the RCQ of the leading connection (since the current connection
928  *   has been completely removed from controller memory).
929  *
930  * RAMROD_CMD_ID_ETH_PORT_DEL
931  *   Used to tear down the leading connection prior to driver unload,
932  *   typically fp[0].  Completes as an index increment of the CSTORM on the
933  *   default status block.
934  *
935  * RAMROD_CMD_ID_ETH_FORWARD_SETUP
936  *   Used for connection offload.  Completes on the RCQ of the multi-queue
937  *   RSS connection that is being offloaded.  (Not currently used under
938  *   FreeBSD.)
939  *
940  * There can only be one command pending per function.
