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 * occurred while driver was down) * e. PF enable in the CFC (WEAK + STRONG) * f. Timers scan enable * 3. PF driver unload flow: * a.
