[openib-general] [PATCH/iproute2] Add support for IP-over-InfiniBand

[Roland Dreier]

This trivial patch adds support for displaying InfiniBand link
addresses.  With the patch, output of "ip addr" changes from

    15: ib0: <BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast qlen 128
        link/[32] 00:00:04:04:fe:80:00:00:00:00:00:00:00:02:c9:01:07:8c:e4:61 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff

to

    15: ib0: <BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast qlen 128
        link/infiniband 00:00:04:04:fe:80:00:00:00:00:00:00:00:02:c9:01:07:8c:e4:61 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff

(Recent libc headers have ARPHRD_INFINIBAND defined -- for example,
they are in libc6-dev on my Debian Sarge system)

Thanks,
  Roland
