Right, not every driver supports such un-aligned buffer.

I am not familiar with RDMA, but from the trace we have done so far,
it is highly related with iser driver.

Hi Stephen,

Do you need the iSER protocol? I think that the NVMeOF and SRP drivers also support RoCE and that these align data buffers on a 512 byte boundary.
