I told you, if a driver requires vendor specific information then include it as private data in the grh. I keep saying this: computing the gid index is not optional. If a drive can't do it efficiently then too bad, it has to go the long way around. >> I think mlx made a big mistake returning network_type instead of gid >> index, and I don't want to see that error enshrined in our API. >> > returning gid_index is wrong because it forces CQ pollers to be aware > of the entire table. Like I already mentioned, the GID table is a HW > resource that can be divided and handed to multiple VMs, Please. If HW virt stuff can't sort this out it is broken, there are many trivial solutions.
