/*
 * Post a slowpath command.
 *
 * A slowpath command is used to propagate 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.

 * In E2 there is a bug in the timers block that can cause function 6 / 7
 * (i.e. vnic3) to start even if it is marked as "scan-off".
 * This occurs when a different function (func2,3) is being marked
 * as "scan-off". Real-life scenario for example: if a driver is being
 * load-unloaded while func6,7 are down. This will cause the timer to access
 * the ilt, translate to a logical address and send a request to read/write.
 * Since the ilt for the function that is down is not valid, this will cause
 * a translation error which is unrecoverable.
 * The Workaround is intended to make sure that when this happens nothing
 * fatal will occur. The workaround:
 *  1.  First PF driver which loads on a path will:
 *      a.  After taking the chip out of reset, by using pretend,
 *          it will write "0" to the following registers of
 *          the other vnics.
 *          REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
 *          REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
 *          REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
 *          And for itself it will write '1' to
 *          PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
 *          dmae-operations (writing to pram for example.)
 *          note: can be done for only function 6,7 but cleaner this
 *            way.
 *      b.  Write zero+valid to the entire ILT.
 *      c.  Init the first_timers_ilt_entry, last_timers_ilt_entry of
 *          VNIC3 (of that port). The range allocated will be the
 *          entire ILT. This is needed to prevent  ILT range error.
 *  2.  Any PF driver load flow:
 *      a.  ILT update with the physical addresses of the allocated
 *          logical pages.
 *      b.  Wait 20msec. - note that this timeout is needed to make
 *          sure there are no requests in one of the PXP internal
 *          queues with "old" ILT addresses.
 *      c.  PF enable in the PGLC.
 *      d.  Clear the was_error of the PF in the PGLC. (could have
 *          occurred while driver was down)
 *      e.  PF enable in the CFC (WEAK + STRONG)
 *      f.  Timers scan enable
 *  3.  PF driver unload flow:
 *      a.  Clear the Timers scan_en.
 *      b.  Polling for scan_on=0 for that PF.
 *      c.  Clear the PF enable bit in the PXP.
 *      d.  Clear the PF enable in the CFC (WEAK + STRONG)
 *      e.  Write zero+valid to all ILT entries (The valid bit must
 *          stay set)
 *      f.  If this is VNIC 3 of a port then also init
 *          first_timers_ilt_entry to zero and last_timers_ilt_entry
 *          to the last enrty in the ILT.
 *
 *      Notes:
 *      Currently the PF error in the PGLC is non recoverable.
 *      In the future the there will be a recovery routine for this error.
 *      Currently attention is masked.
 *      Having an MCP lock on the load/unload process does not guarantee that
 *      there is no Timer disable during Func6/7 enable. This is because the
 *      Timers scan is currently being cleared by the MCP on FLR.
 *      Step 2.d can be done only for PF6/7 and the driver can also check if
 *      there is error before clearing it. But the flow above is simpler and
 *      more general.
 *      All ILT entries are written by zero+valid and not just PF6/7
 *      ILT entries since in the future the ILT entries allocation for
 *      PF-s might be dynamic.
