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