RDMA/efa: Fix unsupported page sizes in device
[ Upstream commit 866422cdddcdf59d8c68e9472d49ba1be29b5fcf ]
Device uses 4KB size blocks for user pages indirect list while the
driver creates those blocks with the size of PAGE_SIZE of the kernel. On
kernels with PAGE_SIZE different than 4KB (ARM RHEL), this leads to a
failure on register MR with indirect list because of the miss
communication between driver and device.
Fixes: 40909f664d27 ("RDMA/efa: Add EFA verbs implementation")
