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 offset.

When adding a new GID compare the vlan along with the GID and type. This allows vlan's to have GIDs that alias each other, such as the default GID. Otherwise they the GID cache view can become inconsistent with the HW view. Link: https://lore.kernel.org/r/20191115154457.247763-1-leon@kernel.orgSigned-off-by:

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.

We cannot rely on the entry memcpy as we only copy the actual size of the command, the rest of the bytes must be memset to zero. Currently providing non-zero memory will not have any user visible impact. However, since admin commands are extendable (in a backwards compatible way) everything beyond the size of the command must be cleared to prevent issues in the future.

Add support for flow steering counters action with a non-base counter ID (offset) for bulk counters. When creating a flow counter object, save the bulk value. This value is used when a flow action with a non-base counter ID is requested - to validate that the required offset is in the range of the allocated bulk.
