2270 * A slowpath command is used to propogate a configuration change through
2271 * the controller in a controlled manner, allowing each STORM processor and
2272 * other H/W blocks to phase in the change. The commands sent on the
2273 * slowpath are referred to as ramrods. Depending on the ramrod used the
2274 * completion of the ramrod will occur in different ways. Here's a
2275 * breakdown of ramrods and how they complete:
2277 * RAMROD_CMD_ID_ETH_PORT_SETUP
2278 * Used to setup the leading connection on a port. Completes on the
2279 * Receive Completion Queue (RCQ) of that port (typically fp[0]).
2281 * RAMROD_CMD_ID_ETH_CLIENT_SETUP
2282 * Used to setup an additional connection on a port. Completes on the
2283 * RCQ of the multi-queue/RSS connection being initialized.
2285 * RAMROD_CMD_ID_ETH_STAT_QUERY
2286 * Used to force the storm processors to update the statistics database
2287 * in host memory. This ramrod is send on the leading connection CID and
2288 * completes as an index increment of the CSTORM on the default status
2291 * RAMROD_CMD_ID_ETH_UPDATE
2292 * Used to update the state of the leading connection, usually to udpate
2293 * the RSS indirection table. Completes on the RCQ of the leading
2294 * connection. (Not currently used under FreeBSD until OS support becomes
2297 * RAMROD_CMD_ID_ETH_HALT
2298 * Used when tearing down a connection prior to driver unload. Completes
2299 * on the RCQ of the multi-queue/RSS connection being torn down. Don't
2300 * use this on the leading connection.
2302 * RAMROD_CMD_ID_ETH_SET_MAC
2303 * Sets the Unicast/Broadcast/Multicast used by the port. Completes on
2304 * the RCQ of the leading connection.
2306 * RAMROD_CMD_ID_ETH_CFC_DEL
2307 * Used when tearing down a conneciton prior to driver unload. Completes
2308 * on the RCQ of the leading connection (since the current connection
2309 * has been completely removed from controller memory).
2311 * RAMROD_CMD_ID_ETH_PORT_DEL
2312 * Used to tear down the leading connection prior to driver unload,
2313 * typically fp[0]. Completes as an index increment of the CSTORM on the
2314 * default status block.
2316 * RAMROD_CMD_ID_ETH_FORWARD_SETUP
2317 * Used for connection offload. Completes on the RCQ of the multi-queue
2318 * RSS connection that is being offloaded. (Not currently used under
2321 * There can only be one command pending per function.

16912 * dmae-operations (writing to pram for example.)
16913 * note: can be done for only function 6,7 but cleaner this
16915 * b. Write zero+valid to the entire ILT.
16916 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
16917 * VNIC3 (of that port). The range allocated will be the
16918 * entire ILT. This is needed to prevent ILT range error.
16919 * 2. Any PF driver load flow:
16920 * a. ILT update with the physical addresses of the allocated
16922 * b. Wait 20msec. - note that this timeout is needed to make
16923 * sure there are no requests in one of the PXP internal
16924 * queues with "old" ILT addresses.
16925 * c. PF enable in the PGLC.
16926 * d. Clear the was_error of the PF in the PGLC. (could have
16927 * occurred while driver was down)
16928 * e. PF enable in the CFC (WEAK + STRONG)
16929 * f. Timers scan enable
