[openib-general] [PATCH] Enable inet6 on ib interface

[Roland Dreier]

By the way, can anyone explain the following to me (an IPv6 rookie):

    # ping6 -I ib0 fe80::202:c901:78c:e461
    PING fe80::202:c901:78c:e461(fe80::202:c901:78c:e461) from fe80::202:c901:7fc:c711 ib0: 56 data bytes
    64 bytes from fe80::202:c901:78c:e461: icmp_seq=1 ttl=64 time=32.2 ms
    64 bytes from fe80::202:c901:78c:e461: icmp_seq=2 ttl=64 time=14.7 ms
    64 bytes from fe80::202:c901:78c:e461: icmp_seq=3 ttl=64 time=14.6 ms

    --- fe80::202:c901:78c:e461 ping statistics ---
    3 packets transmitted, 3 received, 0% packet loss, time 2001ms
    rtt min/avg/max/mdev = 14.682/20.557/32.274/8.286 ms

    # ping6 fe80::202:c901:78c:e461
    connect: Invalid argument

    # ssh -6 fe80::202:c901:78c:e461
    ssh: connect to host fe80::202:c901:78c:e461 port 22: Invalid argument

ssh works fine if I assign non-autoconfig'ed addresses.

Ethernet behaves the same way so I don't think it's something to do
with the IPoIB driver, but I would like to understand it better (if
only for my own edification).

Thanks,
  Roland
