[PATCH] xprtrdma: mind the device's max fast register page list depth

2014-04-10 Thread Steve Wise
Some rdma devices don't support a fast register page list depth of at least RPCRDMA_MAX_DATA_SEGS. So xprtrdma needs to chunk its fast register regions according to the minimum of the device max supported depth or RPCRDMA_MAX_DATA_SEGS. Signed-off-by: Steve Wise sw...@opengridcomputing.com ---
