6097 * This occurs when a different function (func2,3) is being marked
6098 * as "scan-off". Real-life scenario for example: if a driver is being
6099 * load-unloaded while func6,7 are down. This will cause the timer to access
6100 * the ilt, translate to a logical address and send a request to read/write.
6101 * Since the ilt for the function that is down is not valid, this will cause
6102 * a translation error which is unrecoverable.
6103 * The Workaround is intended to make sure that when this happens nothing fatal
6104 * will occur. The workaround:
6105 * 1. First PF driver which loads on a path will:
6106 * a. After taking the chip out of reset, by using pretend,
6107 * it will write "0" to the following registers of

6110 * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
6111 * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
6112 * And for itself it will write '1' to
6113 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
6114 * dmae-operations (writing to pram for example.)
6115 * note: can be done for only function 6,7 but cleaner this
6116 * way.
6117 * b. Write zero+valid to the entire ILT.
6118 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
6119 * VNIC3 (of that port). The range allocated will be the
6120 * entire ILT. This is needed to prevent ILT range error.
6121 * 2. Any PF driver load flow:
6122 * a. ILT update with the physical addresses of the allocated
6123 * logical pages.
6124 * b. Wait 20msec. - note that this timeout is needed to make
6125 * sure there are no requests in one of the PXP internal
6126 * queues with "old" ILT addresses.
6127 * c. PF enable in the PGLC.
6128 * d. Clear the was_error of the PF in the PGLC. (could have
6129 * occured while driver was down)
6130 * e. PF enable in the CFC (WEAK + STRONG)
6131 * f. Timers scan enable
6132 * 3. PF driver unload flow:
6133 * a. Clear the Timers scan_en.
6134 * b. Polling for scan_on=0 for that PF.
6135 * c. Clear the PF enable bit in the PXP.
6136 * d. Clear the PF enable in the CFC (WEAK + STRONG)
6137 * e. Write zero+valid to all ILT entries (The valid bit must
6138 * stay set)
6139 * f. If this is VNIC 3 of a port then also init
6140 * first_timers_ilt_entry to zero and last_timers_ilt_entry
6141 * to the last enrty in the ILT.
6142 *
6143 * Notes:
6144 * Currently the PF error in the PGLC is non recoverable.
6145 * In the future the there will be a recovery routine for this error.
6146 * Currently attention is masked.
6147 * Having an MCP lock on the load/unload process does not guarantee that
6148 * there is no Timer disable during Func6/7 enable. This is because the
6149 * Timers scan is currently being cleared by the MCP on FLR.
6150 * Step 2.d can be done only for PF6/7 and the driver can also check if
6151 * there is error before clearing it. But the flow above is simpler and
6152 * more general.
6153 * All ILT entries are written by zero+valid and not just PF6/7
6154 * ILT entries since in the future the ILT entries allocation for
6155 * PF-s might be dynamic.
