rdma link has started to fail today reporting an error as follows after working before.
bob@ubunto-21:~$ sudo rdma link add rxe0 type rxe netdev enp0s3
error: Invalid argument
bob@ubunto-21:
Nothing has changed in the past day or two except I pulled recent changes into rdma-core. This runs after
typing
export LD_LIBRARY_PATH=/home/bob/src/rdma-core/build/lib/:/usr/local/lib:/usr/lib
which is also the same. Any ideas?
Bob

Update. I then recompiled the kernel after pulling latest changes and now it works. In theory this shouldn't be necessary. The kernel APIs should be beckwards compatible.

I don't think anything has changed here in a long time, so I have no
guess
'rdma link' has no relation to rdma-core either
Perhaps your kernel got in a bad state?
