Sean, Bart - any comment on the API before Sagi sits down to code the
iSER changes?
Hello Or,
Will this API ever be supported by other Mellanox RDMA drivers than
mlx5, e.g. mlx4 ? Will this API ever be supported by a Mellanox HCA that
supports RoCE ? Additionally, do you perhaps know whether any other RDMA
vendors have plans to implement this API for their RDMA HCA's ? Drivers
like the iSER and SRP initiator and target drivers have been implemented
on top of the RDMA API and support all hardware that implements the RDMA
API. Since this patch series adds support for the indirect fast memory
registration API for mlx5 only this means that adding support for this
API in block storage drivers also means adding a fall-back path for RDMA
drivers that do not have support for this API. That will make these
block storage drivers harder to maintain, which is something I would
like to avoid.
Bart.
