Our design center for RDS was to support 1meg sized rdma xfers - however
neither the interface nor the implementation are limited.
We have not tested above 1meg for rdma and we only test up 65k for bcopy
xfers.
To support larger xfers some default parameter values would need to be
increased ...
ls /proc/sys/net/rds/ib
max_recv_allocation max_recv_wr max_send_wr max_unsignaled_bytes
max_unsignaled_wr
