 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.
