* Post a slowpath command.
*
* A slowpath command is used to propogate a configuration change through
* the controller in a controlled manner, allowing each STORM processor and
* other H/W blocks to phase in the change. The commands sent on the
* slowpath are referred to as ramrods. Depending on the ramrod used the
* completion of the ramrod will occur in different ways. Here's a
* breakdown of ramrods and how they complete:
*
* RAMROD_CMD_ID_ETH_PORT_SETUP
* Used to setup the leading connection on a port. Completes on the
* Receive Completion Queue (RCQ) of that port (typically fp[0]).
*
* RAMROD_CMD_ID_ETH_CLIENT_SETUP
* Used to setup an additional connection on a port. Completes on the
* RCQ of the multi-queue/RSS connection being initialized.
*
* RAMROD_CMD_ID_ETH_STAT_QUERY
* Used to force the storm processors to update the statistics database
* in host memory. This ramrod is send on the leading connection CID and
* completes as an index increment of the CSTORM on the default status
* block.
*
* RAMROD_CMD_ID_ETH_UPDATE
* Used to update the state of the leading connection, usually to udpate
* the RSS indirection table. 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. (Not currently used under
* FreeBSD.)
*
* There can only be one command pending per function.
*
* Returns:
* 0 = Success, !0 = Failure.
