++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ERRATA (Open Issues)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

- 44077: FCoE LUN is not listing during Windows Server 2022 installation phase.

- 44048: Unable to format the iSCSI boot LUN (Microsoft/LIO Targets) during 
         Windows 2019 OS installation. 

- 44047: FCoE BIOS Initialization fails for T6225-OCP3 Adapter.

- 44046: iSCSI BIOS Initialization fails for T6225-OCP3 Adapter.

- 44045: Link status is shown as "Down" for Chelsio interface while iPXE boot.

- 40158: Machine keeps rebooting in legacy mode with EFI based OS already 
         present on LUN.

- 39995: Option ROM loading with adapters having different versions.

NOTE: With multiple adapters having different types and versions of Option ROMs, 
      the loading of Option ROM depends on factors like System type (Legacy only, 
      uEFI or dual bios), versions, first device initializing etc. So, it is 
      highly recommended to use the same Option ROM (type and version) on all
      Chelsio adapters in the system.  

- 39895: iSCSI boot should allow multiple target and luns to save as boot device.

- 36680: Need support for AARCH64 in uEFI driver.

- 35708: [Lenovo]: HII is currently not supported on latest uEFI v2.6 machines.

Workaround: Use "drvcfg -s" from uEFI shell to configure the adapter.    

- 23705: Need to show the PHY Firmware version of T5 BT cards.

- 23143: [HII] Behaviour on IBM x3850 Gen 6 needs few modifications.
