2259 * A slowpath command is used to propagate a configuration change through
2260 * the controller in a controlled manner, allowing each STORM processor and
2261 * other H/W blocks to phase in the change. The commands sent on the
2262 * slowpath are referred to as ramrods. Depending on the ramrod used the
2263 * completion of the ramrod will occur in different ways. Here's a
2264 * breakdown of ramrods and how they complete:
2266 * RAMROD_CMD_ID_ETH_PORT_SETUP
2267 * Used to setup the leading connection on a port. Completes on the
2268 * Receive Completion Queue (RCQ) of that port (typically fp[0]).
2270 * RAMROD_CMD_ID_ETH_CLIENT_SETUP
2271 * Used to setup an additional connection on a port. Completes on the
2272 * RCQ of the multi-queue/RSS connection being initialized.
2274 * RAMROD_CMD_ID_ETH_STAT_QUERY
2275 * Used to force the storm processors to update the statistics database
2276 * in host memory. This ramrod is send on the leading connection CID and
2277 * completes as an index increment of the CSTORM on the default status
2280 * RAMROD_CMD_ID_ETH_UPDATE
2281 * Used to update the state of the leading connection, usually to udpate
2282 * the RSS indirection table. Completes on the RCQ of the leading
2283 * connection. (Not currently used under FreeBSD until OS support becomes
2286 * RAMROD_CMD_ID_ETH_HALT
2287 * Used when tearing down a connection prior to driver unload. Completes
2288 * on the RCQ of the multi-queue/RSS connection being torn down. Don't
2289 * use this on the leading connection.
2291 * RAMROD_CMD_ID_ETH_SET_MAC
2292 * Sets the Unicast/Broadcast/Multicast used by the port. Completes on
2293 * the RCQ of the leading connection.
2295 * RAMROD_CMD_ID_ETH_CFC_DEL
2296 * Used when tearing down a conneciton prior to driver unload. Completes
2297 * on the RCQ of the leading connection (since the current connection
2298 * has been completely removed from controller memory).
2300 * RAMROD_CMD_ID_ETH_PORT_DEL
2301 * Used to tear down the leading connection prior to driver unload,
2302 * typically fp[0]. Completes as an index increment of the CSTORM on the
2303 * default status block.
2305 * RAMROD_CMD_ID_ETH_FORWARD_SETUP
2306 * Used for connection offload. Completes on the RCQ of the multi-queue
2307 * RSS connection that is being offloaded. (Not currently used under
2310 * There can only be one command pending per function.

16859 * load-unloaded while func6,7 are down. This will cause the timer to access

16861 * Since the ilt for the function that is down is not valid, this will cause

16865 * 1. First PF driver which loads on a path will:
16866 * a. After taking the chip out of reset, by using pretend,
16867 * it will write "0" to the following registers of

16873 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
16874 * dmae-operations (writing to pram for example.)
16875 * note: can be done for only function 6,7 but cleaner this
16877 * b. Write zero+valid to the entire ILT.
16878 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
16879 * VNIC3 (of that port). The range allocated will be the
16880 * entire ILT. This is needed to prevent ILT range error.
16881 * 2. Any PF driver load flow:
16882 * a. ILT update with the physical addresses of the allocated
16884 * b. Wait 20msec. - note that this timeout is needed to make
16885 * sure there are no requests in one of the PXP internal
16886 * queues with "old" ILT addresses.
16887 * c. PF enable in the PGLC.
16888 * d. Clear the was_error of the PF in the PGLC. (could have
16889 * occurred while driver was down)
16890 * e. PF enable in the CFC (WEAK + STRONG)
16891 * f. Timers scan enable
16892 * 3. PF driver unload flow:
16893 * a. Clear the Timers scan_en.
16894 * b. Polling for scan_on=0 for that PF.
16895 * c. Clear the PF enable bit in the PXP.
16896 * d. Clear the PF enable in the CFC (WEAK + STRONG)
16897 * e. Write zero+valid to all ILT entries (The valid bit must
16899 * f. If this is VNIC 3 of a port then also init
16900 * first_timers_ilt_entry to zero and last_timers_ilt_entry
16901 * to the last enrty in the ILT.
16904 * Currently the PF error in the PGLC is non recoverable.
16905 * In the future the there will be a recovery routine for this error.
16906 * Currently attention is masked.
16907 * Having an MCP lock on the load/unload process does not guarantee that
16908 * there is no Timer disable during Func6/7 enable. This is because the
16909 * Timers scan is currently being cleared by the MCP on FLR.
16910 * Step 2.d can be done only for PF6/7 and the driver can also check if
16911 * there is error before clearing it. But the flow above is simpler and
16913 * All ILT entries are written by zero+valid and not just PF6/7
