2018-08-18hw/rdma: Bugfix - Support non-aligned buffersYuval Shaia
RDMA application can provide non-aligned buffers to be registered. In such case the DMA address passed by driver is pointing to the beginning of the physical address of the mapped page so we can't distinguish between two addresses from the same page. Fix it by keeping the offset of the virtual address in mr->virt.
