Hi All,
Weirdness with a RoCE interface - verbs is not playing ball and is
complaining about the inet6 address not matching up:
2017-09-02_07:46:01.376+0100: [I] VERBS RDMA starting with verbsRdmaCm=yes

nspdQueues 1)).

2017-09-02_07:46:01.391+0100: [E] VERBS RDMA failed to start, no valid

Anyone run into this before? I have another node imaged the *exact* same
way and no dice. Have tried a variety of drivers, cards, etc, same result
every time.
Cheers,
Barry
