 930  * other H/W blocks to phase in the change.  The commands sent on the
 931  * slowpath are referred to as ramrods.  Depending on the ramrod used the
 932  * completion of the ramrod will occur in different ways.  Here's a
 933  * breakdown of ramrods and how they complete:
 934  *
 935  * RAMROD_CMD_ID_ETH_PORT_SETUP
 936  *   Used to setup the leading connection on a port.  Completes on the
 937  *   Receive Completion Queue (RCQ) of that port (typically fp[0]).
 938  *
 939  * RAMROD_CMD_ID_ETH_CLIENT_SETUP
 940  *   Used to setup an additional connection on a port.  Completes on the
 941  *   RCQ of the multi-queue/RSS connection being initialized.
 942  *
 943  * RAMROD_CMD_ID_ETH_STAT_QUERY
 944  *   Used to force the storm processors to update the statistics database
 945  *   in host memory.  This ramrod is send on the leading connection CID and
 946  *   completes as an index increment of the CSTORM on the default status
 947  *   block.
 948  *
 949  * RAMROD_CMD_ID_ETH_UPDATE
 950  *   Used to update the state of the leading connection, usually to udpate
 951  *   the RSS indirection table.  Completes on the RCQ of the leading
 952  *   connection. (Not currently used under FreeBSD until OS support becomes
 953  *   available.)
 954  *
 955  * RAMROD_CMD_ID_ETH_HALT
 956  *   Used when tearing down a connection prior to driver unload.  Completes
 957  *   on the RCQ of the multi-queue/RSS connection being torn down.  Don't
 958  *   use this on the leading connection.
 959  *
 960  * RAMROD_CMD_ID_ETH_SET_MAC
 961  *   Sets the Unicast/Broadcast/Multicast used by the port.  Completes on
 962  *   the RCQ of the leading connection.
 963  *
 964  * RAMROD_CMD_ID_ETH_CFC_DEL
 965  *   Used when tearing down a conneciton prior to driver unload.  Completes
 966  *   on the RCQ of the leading connection (since the current connection
 967  *   has been completely removed from controller memory).
 968  *
 969  * RAMROD_CMD_ID_ETH_PORT_DEL
 970  *   Used to tear down the leading connection prior to driver unload,
 971  *   typically fp[0].  Completes as an index increment of the CSTORM on the
 972  *   default status block.
 973  *
 974  * RAMROD_CMD_ID_ETH_FORWARD_SETUP
 975  *   Used for connection offload.  Completes on the RCQ of the multi-queue
 976  *   RSS connection that is being offloaded.  (Not currently used under
 977  *   FreeBSD.)
 978  *
 979  * There can only be one command pending per function.

10234  * Since the ilt for the function that is down is not valid, this will cause
10235  * a translation error which is unrecoverable.
10236  * The Workaround is intended to make sure that when this happens nothing
10237  * fatal will occur. The workaround:
10238  *  1.  First PF driver which loads on a path will:
10239  *      a.  After taking the chip out of reset, by using pretend,
10240  *          it will write "0" to the following registers of
10241  *          the other vnics.
10242  *          REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
10243  *          REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
10244  *          REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
10245  *          And for itself it will write '1' to
10246  *          PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
10247  *          dmae-operations (writing to pram for example.)
10248  *          note: can be done for only function 6,7 but cleaner this
10249  *            way.
10250  *      b.  Write zero+valid to the entire ILT.
10251  *      c.  Init the first_timers_ilt_entry, last_timers_ilt_entry of
10252  *          VNIC3 (of that port). The range allocated will be the
10253  *          entire ILT. This is needed to prevent  ILT range error.
10254  *  2.  Any PF driver load flow:
10255  *      a.  ILT update with the physical addresses of the allocated
10256  *          logical pages.
10257  *      b.  Wait 20msec. - note that this timeout is needed to make
10258  *          sure there are no requests in one of the PXP internal
10259  *          queues with "old" ILT addresses.
10260  *      c.  PF enable in the PGLC.
10261  *      d.  Clear the was_error of the PF in the PGLC. (could have
10262  *          occurred while driver was down)
10263  *      e.  PF enable in the CFC (WEAK + STRONG)
10264  *      f.  Timers scan enable
10265  *  3.  PF driver unload flow:
10266  *      a.  Clear the Timers scan_en.
10267  *      b.  Polling for scan_on=0 for that PF.
10268  *      c.  Clear the PF enable bit in the PXP.
10269  *      d.  Clear the PF enable in the CFC (WEAK + STRONG)
10270  *      e.  Write zero+valid to all ILT entries (The valid bit must
10271  *          stay set)
10272  *      f.  If this is VNIC 3 of a port then also init
10273  *          first_timers_ilt_entry to zero and last_timers_ilt_entry
10274  *          to the last enrty in the ILT.
10275  *
10276  *      Notes:
10277  *      Currently the PF error in the PGLC is non recoverable.
10278  *      In the future the there will be a recovery routine for this error.
10279  *      Currently attention is masked.
10280  *      Having an MCP lock on the load/unload process does not guarantee that
10281  *      there is no Timer disable during Func6/7 enable. This is because the
10282  *      Timers scan is currently being cleared by the MCP on FLR.
10283  *      Step 2.d can be done only for PF6/7 and the driver can also check if
10284  *      there is error before clearing it. But the flow above is simpler and
10285  *      more general.
10286  *      All ILT entries are written by zero+valid and not just PF6/7
10287  *      ILT entries since in the future the ILT entries allocation for
10288  *      PF-s might be dynamic.
