Subject: scsi: lpfc: Correct WQ creation for pagesize
From: James Smart <jsmart2021@xxxxxxxxx>
commit 8ea73db486cda442f0671f4bc9c03a76be398a28 upstream.
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.
