When running against rdma-core that doesn't support doorbell recovery, the
rdma_user_mmap_entry won't be allocated for doorbell recovery related
mappings.
We have a flag indicating whether rdma-core supports doorbell recovery or
not which was used during initialization, however some cases didn't check
that the rdma_user_mmap_entry exists before attempting to acquire it's

The cma is currently using a hard-coded value, CMA_IBOE_PACKET_LIFETIME,
for the PacketLifeTime, as it can not be determined from the network.
This value might not be optimal for all networks.
The cma module supports the function rdma_set_ack_timeout to set the ACK
timeout for a QP associated with a connection. As per IBTA 12.7.34 local
ACK timeout = (2 * PacketLifeTime + Local CA’s ACK delay). Assuming a
negligible local ACK delay, we can use PacketLifeTime = local ACK
timeout/2 as a reasonable approximation for RoCE networks.

Normal RDMA WRITE request never returns IB_WC_RNR_RETRY_EXC_ERR to ULPs
because it does not need post receive buffer on the responder side.
Consequently, as an enhancement to normal RDMA WRITE request inside the
hfi1 driver, TID RDMA WRITE request should not return such an error status
to ULPs, although it does receive RNR NAKs from the responder when TID
resources are not available. This behavior is violated when
qp->s_rnr_retry_cnt is set in current hfi1 implementation.
This patch enforces these semantics by avoiding any reaction to the updates
of the RNR QP attributes.
