[PATCH 12/15] mpi3mr: NVMe commands size greater than 8K fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A wrong variable is checked while populating PRP entries in the PRP
page and that results in failure .Hence no PRP entries in the PRP
page were successfully created and any NVMe Encapsulated commands
with PRP of size greater than 8K failed
