* 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.
