Additional Notes For Driver Updates

The following notes are included at the request of a vendor for the listed driver:

lpfc: Locked optics support is enabled for LPE32000 HBAs and all variant HBAs of this architecture. With this capability, these HBAs will detect and enable both Avago or Emulex certified SFP and QSFP optics.

For driver rev 11.0.0.13 and higher unqualified optics will be disabled, the link will not come up, an error message is written to the log file and the lpfc driver will display this message:
```
3176 Port Name [wwpn] Unqualified optics - Replace with Avago optics for Warranty and Technical support
```
For driver rev 11.4.0.7 and higher, Target Queue Depth can be tuned dynamically to control performance or to help manage potential queuing problems. The default Target Queue Depth is 65535, which typically offers the greatest performance. This can be changed to a value in the range 10 to 65535. When changing the Target Queue Depth the new target queue depth remains in effect for a minimum of 40 seconds. Any changes made within the 40 second window are deferred and do not take effect until the 40 second window has passed. Note that the 40 second window may be removed in a future version of this driver module. To change the Target Queue Depth on SCSI Host X run the command:
```
# echo new_value > /sys/class/scsi_host/hostX/lpfc_tgt_queue_depth
```
Replace new_value with an integer between 10 and 65535.
mpt3sas: As of UEK R4U4, the mpt2sas driver has been merged with the mpt3sas driver to provide a single driver module that supports both SAS 2.0 and SAS 3.0 HBAs. Changes have been applied to dracut to correctly handle the module aliases for the migration to a single driver module.
