Subject: [PATCH rdma-next v2 1/2] RDMA/mana_ib: use the correct page table index based on hardware page size

From: [email-masked]
Date: Fri, 30 Aug 2024 08:16:32 -0700

From: Long Li <[email-masked]>

MANA hardware uses 4k page size. When calculating the page table index,
it should use the hardware page size, not the system page size.
