RDMA/irdma: Fix support for 64k pages
Browse files Browse the repository at this point in the history
Virtual QP and CQ require a 4K HW page size but the driver passes
PAGE_SIZE to ib_umem_find_best_pgsz() instead.

Fix this by using the appropriate 4k value in the bitmap passed to
ib_umem_find_best_pgsz().

Fixes: 693a538 ("RDMA/irdma: Split mr alloc and free into new functions")
