 888  *
 889  * A slowpath command is used to propagate 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.
