2249 * A slowpath command is used to propogate a configuration change through
2250 * the controller in a controlled manner, allowing each STORM processor and
2251 * other H/W blocks to phase in the change. The commands sent on the
2252 * slowpath are referred to as ramrods. Depending on the ramrod used the
2253 * completion of the ramrod will occur in different ways. Here's a
2254 * breakdown of ramrods and how they complete:
2256 * RAMROD_CMD_ID_ETH_PORT_SETUP
2257 * Used to setup the leading connection on a port. Completes on the
2258 * Receive Completion Queue (RCQ) of that port (typically fp[0]).
2260 * RAMROD_CMD_ID_ETH_CLIENT_SETUP
2261 * Used to setup an additional connection on a port. Completes on the
2262 * RCQ of the multi-queue/RSS connection being initialized.
2264 * RAMROD_CMD_ID_ETH_STAT_QUERY
2265 * Used to force the storm processors to update the statistics database
2266 * in host memory. This ramrod is send on the leading connection CID and
2267 * completes as an index increment of the CSTORM on the default status
2270 * RAMROD_CMD_ID_ETH_UPDATE
2271 * Used to update the state of the leading connection, usually to udpate
2272 * the RSS indirection table. Completes on the RCQ of the leading
2273 * connection. (Not currently used under FreeBSD until OS support becomes
2276 * RAMROD_CMD_ID_ETH_HALT
2277 * Used when tearing down a connection prior to driver unload. Completes
2278 * on the RCQ of the multi-queue/RSS connection being torn down. Don't
2279 * use this on the leading connection.
2281 * RAMROD_CMD_ID_ETH_SET_MAC
2282 * Sets the Unicast/Broadcast/Multicast used by the port. Completes on
2283 * the RCQ of the leading connection.
2285 * RAMROD_CMD_ID_ETH_CFC_DEL
2286 * Used when tearing down a conneciton prior to driver unload. Completes
2287 * on the RCQ of the leading connection (since the current connection
2288 * has been completely removed from controller memory).
2290 * RAMROD_CMD_ID_ETH_PORT_DEL
2291 * Used to tear down the leading connection prior to driver unload,
2292 * typically fp[0]. Completes as an index increment of the CSTORM on the
2293 * default status block.
2295 * RAMROD_CMD_ID_ETH_FORWARD_SETUP
2296 * Used for connection offload. Completes on the RCQ of the multi-queue
2297 * RSS connection that is being offloaded. (Not currently used under

16751 * This occurs when a different function (func2,3) is being marked
16752 * as "scan-off". Real-life scenario for example: if a driver is being
16753 * load-unloaded while func6,7 are down. This will cause the timer to access
16754 * the ilt, translate to a logical address and send a request to read/write.
16755 * Since the ilt for the function that is down is not valid, this will cause
16756 * a translation error which is unrecoverable.
16757 * The Workaround is intended to make sure that when this happens nothing
16758 * fatal will occur. The workaround:
16759 * 1. First PF driver which loads on a path will:
16760 * a. After taking the chip out of reset, by using pretend,
16761 * it will write "0" to the following registers of

16766 * And for itself it will write '1' to
16767 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
16768 * dmae-operations (writing to pram for example.)
16769 * note: can be done for only function 6,7 but cleaner this
16771 * b. Write zero+valid to the entire ILT.
16772 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
16773 * VNIC3 (of that port). The range allocated will be the
16774 * entire ILT. This is needed to prevent ILT range error.
16775 * 2. Any PF driver load flow:
16776 * a. ILT update with the physical addresses of the allocated
16778 * b. Wait 20msec. - note that this timeout is needed to make
16779 * sure there are no requests in one of the PXP internal
16780 * queues with "old" ILT addresses.
16781 * c. PF enable in the PGLC.
16782 * d. Clear the was_error of the PF in the PGLC. (could have
16783 * occurred while driver was down)
16784 * e. PF enable in the CFC (WEAK + STRONG)
16785 * f. Timers scan enable
16786 * 3. PF driver unload flow:
16787 * a. Clear the Timers scan_en.
16788 * b. Polling for scan_on=0 for that PF.
16789 * c. Clear the PF enable bit in the PXP.
16790 * d. Clear the PF enable in the CFC (WEAK + STRONG)
16791 * e. Write zero+valid to all ILT entries (The valid bit must
16793 * f. If this is VNIC 3 of a port then also init
16794 * first_timers_ilt_entry to zero and last_timers_ilt_entry
16795 * to the last enrty in the ILT.
16798 * Currently the PF error in the PGLC is non recoverable.
16799 * In the future the there will be a recovery routine for this error.
16800 * Currently attention is masked.
16801 * Having an MCP lock on the load/unload process does not guarantee that
16802 * there is no Timer disable during Func6/7 enable. This is because the
16803 * Timers scan is currently being cleared by the MCP on FLR.
16804 * Step 2.d can be done only for PF6/7 and the driver can also check if
16805 * there is error before clearing it. But the flow above is simpler and
16807 * All ILT entries are written by zero+valid and not just PF6/7
16808 * ILT entries since in the future the ILT entries allocation for
16809 * PF-s might be dynamic.
