[PATCH v2 01/18] lpfc: Correct WQ creation for pagesize

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

 



Correct WQ creation for pagesize

The driver was calculating the adapter command pagesize indicator from
the system pagesize. However, the buffers the driver allocates are only
one size (SLI4_PAGE_SIZE), so no calculation was necessary.
