This is because of a bug in Red Hat Enterprise Linux 4:

    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180980

(*no* program using libpcap can capture on IP-over-IB interfaces).

The change that broke this isn't in the mainstream Linux kernel - it's only in
the kernel in RHEL 4.

According to the Red Hat Bugzilla entry above, they'll be fixing that in a
future RHEL 4 version.  To work around the problem, either change the first
piece of code handling SIOCGIFHWADDR in net/core/dev.c to

                case SIOCGIFHWADDR:
                        if (!dev->addr_len)
                                memset(ifr->ifr_hwaddr.sa_data, 0, sizeof
ifr->ifr_hwaddr.sa_data);
                        else
                                memcpy(ifr->ifr_hwaddr.sa_data, dev->dev_addr,
                                       min(sizeof ifr->ifr_hwaddr.sa_data,
(size_t) dev->addr_len));
                        ifr->ifr_hwaddr.sa_family = dev->type;
                        return 0;

or just upgrade to a more recent kernel, such as 2.6.10, which *already* works
like that.
