Subject: [PATCH] scsi: mpt3sas: Fix module parameter max_msix_vectors
Git-commit: 9e64fd1e65f72d229f96fcf390576e772770a01c
Patch-mainline: v5.5-rc1
References: bsc#1156632,jsc#SLE-10717
Load driver with module parameter "max_msix_vectors". Value provided in
module parameter is not used by mpt3sas driver. Driver loads with max
controller supported MSI-X value.
In _base_alloc_irq_vectors use reply_queue_count which is determined using
user provided msix value insted of ioc->msix_vector_count which tells max
supported msix value of the controller.
