Hi

I have a question regarding a untagged union field added in commit:
https://github.com/linux-rdma/rdma-core/commit/f67fa98d3c0cb78c95f84301572eb93989d4b0f9

Specifically the union in the 'ibv_send_wr' structure:
https://github.com/linux-rdma/rdma-core/blob/master/libibverbs/verbs.h#L1097-L1100

We have a golang wrapper library in order to make use of infiniband in our system. However golang can only interface with tagged unions.

Is it possible to tag that union?

Or should I just send in a patch with it tagged?

Regards,
Jacques Marais

No, it is 'api' that it remain untagged
