+ * Post a slowpath command.

+ * A slowpath command is used to propagate a configuration change through

+ * 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.

+ * 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);

+ * 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
