Thanks, Dmitry, for mentioning the dependency

Hi Martin,

After addressing the review comments for v5, there has been a change in 
the patch order.

In the latest patchset (v6), Patch 2 (SCSI patch) is now required for 
the functional dependency of the subsequent PHY patches (Patch 3 to 
Patch 9).

Patch 1 (SCSI patch) addresses an existing issue and does not depend on 
any other changes.

Regards,
Nitin
