Santosh Shilimkar	5601245931	RDS: IB: split the mr registration and invalidation path ... MR invalidation in RDS is done in background thread and not in data path like registration. So break the dependency between them which helps to remove the performance bottleneck. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@oracle.com>	2017-01-02 14:02:47 -08:00

Avinash Repaka	1659185fb4	RDS: IB: Support Fastreg MR (FRMR) memory registration mode ... Fastreg MR(FRMR) is another method with which one can register memory to HCA. Some of the newer HCAs supports only fastreg mr mode, so we need to add support for it to have RDS functional on them.
