| H A D | nvme-rdma.h | 44c3c625 Wed Sep 22 16:55:35 CDT 2021 Max Gurtovoy <mgurtovoy@nvidia.com> nvme-rdma: limit the maximal queue size for RDMA controllers
Corrent limit of 1024 isn't valid for some of the RDMA based ctrls. In
case the target expose a cap of larger amount of entries (e.g. 1024),
the initiator may fail to create a QP with this size. Thus limit to a
value that works for all RDMA adapters.
Future general solution should use RDMA/core API to calculate this size
according to device capabilities and number of WRs needed per NVMe IO
request.
