2262 * A slowpath command is used to propogate a configuration change through
2263 * the controller in a controlled manner, allowing each STORM processor and
2264 * other H/W blocks to phase in the change. The commands sent on the
2265 * slowpath are referred to as ramrods. Depending on the ramrod used the
2266 * completion of the ramrod will occur in different ways. Here's a
2267 * breakdown of ramrods and how they complete:
2269 * RAMROD_CMD_ID_ETH_PORT_SETUP
2270 * Used to setup the leading connection on a port. Completes on the
2271 * Receive Completion Queue (RCQ) of that port (typically fp[0]).
2273 * RAMROD_CMD_ID_ETH_CLIENT_SETUP
2274 * Used to setup an additional connection on a port. Completes on the
2275 * RCQ of the multi-queue/RSS connection being initialized.
2277 * RAMROD_CMD_ID_ETH_STAT_QUERY
2278 * Used to force the storm processors to update the statistics database
2279 * in host memory. This ramrod is send on the leading connection CID and
2280 * completes as an index increment of the CSTORM on the default status
2283 * RAMROD_CMD_ID_ETH_UPDATE
2284 * Used to update the state of the leading connection, usually to udpate
2285 * the RSS indirection table. Completes on the RCQ of the leading
2286 * connection. (Not currently used under FreeBSD until OS support becomes
2289 * RAMROD_CMD_ID_ETH_HALT
2290 * Used when tearing down a connection prior to driver unload. Completes
2291 * on the RCQ of the multi-queue/RSS connection being torn down. Don't
2292 * use this on the leading connection.
2294 * RAMROD_CMD_ID_ETH_SET_MAC
2295 * Sets the Unicast/Broadcast/Multicast used by the port. Completes on
2296 * the RCQ of the leading connection.
2298 * RAMROD_CMD_ID_ETH_CFC_DEL
2299 * Used when tearing down a conneciton prior to driver unload. Completes
2300 * on the RCQ of the leading connection (since the current connection
2301 * has been completely removed from controller memory).
2303 * RAMROD_CMD_ID_ETH_PORT_DEL
2304 * Used to tear down the leading connection prior to driver unload,
2305 * typically fp[0]. Completes as an index increment of the CSTORM on the
2306 * default status block.
2308 * RAMROD_CMD_ID_ETH_FORWARD_SETUP
2309 * Used for connection offload. Completes on the RCQ of the multi-queue
2310 * RSS connection that is being offloaded. (Not currently used under
2313 * There can only be one command pending per function.

16919 * as "scan-off". Real-life scenario for example: if a driver is being
16920 * load-unloaded while func6,7 are down. This will cause the timer to access

16922 * Since the ilt for the function that is down is not valid, this will cause

16926 * 1. First PF driver which loads on a path will:
16927 * a. After taking the chip out of reset, by using pretend,
16928 * it will write "0" to the following registers of

16934 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
16935 * dmae-operations (writing to pram for example.)
16936 * note: can be done for only function 6,7 but cleaner this
16938 * b. Write zero+valid to the entire ILT.
16939 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
16940 * VNIC3 (of that port). The range allocated will be the
16941 * entire ILT. This is needed to prevent ILT range error.
16942 * 2. Any PF driver load flow:
16943 * a. ILT update with the physical addresses of the allocated
16945 * b. Wait 20msec. - note that this timeout is needed to make
