What happens if you try to do
tcpdump -s 65535 -i ib0
I very strongly suspect you'll get the same "ioctl: Value too large for
defined data type" message.
If so, this is a libpcap issue. I'll send you the URL for a tarball
with the source to a new version of libpcap with better debugging
information (i.e., saying *which* ioctl was having the problem). You'll
have to build that, along with tcpdump, and try capturing with the new
tcpdump.
