This seems like such a small change to enable such a large amount of functionality? Is it really that straightforward?

pkubaj added a comment.Aug 10 2022, 6:07 PM

Before this change, rping on vlan interfaces failed with:

created cm_id 0x80182e000
rdma_bind_addr: No such file or directory
destroy cm_id 0x80182e000

With this patch, it works.

This will have to wait two weeks for review due to vacation!

Change looks OK, but I want to double check it a bit.

Thank you!

Uhm, you actually put wrong authorship (commit author, who is Bartosz Sobczak). I thought you would just accept this review and I would set it myself. I hope Bartosz is ok with losing copyright :)

pkubaj: Sorry about that.

At least I got the differential revision right :-)

I'll send an e-mail out about that !

This is what vacation does to you ;-)

• hselasky added a comment.Aug 22 2022, 9:35 PM

I'll try to get that right when I MFC it!
