 * (i.e. vnic3) to start even if it is marked as "scan-off".
 * This occurs when a different function (func2,3) is being marked
 * as "scan-off". Real-life scenario for example: if a driver is being
 * load-unloaded while func6,7 are down. This will cause the timer to access
 * the ilt, translate to a logical address and send a request to read/write.
 * Since the ilt for the function that is down is not valid, this will cause
 * a translation error which is unrecoverable.
 * The Workaround is intended to make sure that when this happens nothing fatal
 * will occur. The workaround:
 *	1.  First PF driver which loads on a path will:
 *		a.  After taking the chip out of reset, by using pretend,
 *		    it will write "0" to the following registers of
 *		    the other vnics.
 *		    REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
 *		    REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
 *		    REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
 *		    And for itself it will write '1' to
 *		    PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
 *		    dmae-operations (writing to pram for example.)
 *		    note: can be done for only function 6,7 but cleaner this
 *			  way.
 *		b.  Write zero+valid to the entire ILT.
 *		c.  Init the first_timers_ilt_entry, last_timers_ilt_entry of
 *		    VNIC3 (of that port). The range allocated will be the
 *		    entire ILT. This is needed to prevent  ILT range error.
 *	2.  Any PF driver load flow:
 *		a.  ILT update with the physical addresses of the allocated
 *		    logical pages.
 *		b.  Wait 20msec. - note that this timeout is needed to make
 *		    sure there are no requests in one of the PXP internal
 *		    queues with "old" ILT addresses.
 *		c.  PF enable in the PGLC.
 *		d.  Clear the was_error of the PF in the PGLC. (could have
 *		    occured while driver was down)
 *		e.  PF enable in the CFC (WEAK + STRONG)
 *		f.  Timers scan enable
 *	3.  PF driver unload flow:
 *		a.  Clear the Timers scan_en.
 *		b.  Polling for scan_on=0 for that PF.
 *		c.  Clear the PF enable bit in the PXP.
 *		d.  Clear the PF enable in the CFC (WEAK + STRONG)
 *		e.  Write zero+valid to all ILT entries (The valid bit must
 *		    stay set)
 *		f.  If this is VNIC 3 of a port then also init
 *		    first_timers_ilt_entry to zero and last_timers_ilt_entry
 *		    to the last enrty in the ILT.
 *
 *	Notes:
 *	Currently the PF error in the PGLC is non recoverable.
 *	In the future the there will be a recovery routine for this error.
 *	Currently attention is masked.
 *	Having an MCP lock on the load/unload process does not guarantee that
 *	there is no Timer disable during Func6/7 enable. This is because the
 *	Timers scan is currently being cleared by the MCP on FLR.
 *	Step 2.d can be done only for PF6/7 and the driver can also check if
 *	there is error before clearing it. But the flow above is simpler and
 *	more general.
 *	All ILT entries are written by zero+valid and not just PF6/7
 *	ILT entries since in the future the ILT entries allocation for
 *	PF-s might be dynamic.
