IPoIB is working in general, but tcpdump does not work with IPoIB. # tcpdump -i ib0 tcpdump: ioctl: Value too large for defined data type strace says: ioctl(3, SIOCGIFINDEX, {ifr_name="lo", ifr_index=1}) = 0 ioctl(3, SIOCGIFHWADDR, {ifr_name="ib0", ???}) = -1 EOVERFLOW (Value too large f or defined data type) close(3) = 0 write(2, "tcpdump: ", 9tcpdump: ) = 9 write(2, "ioctl: Value too large for defin"..., 44ioctl: Value too large for def ined data type) = 44 Version-Release number of selected component (if applicable): tcpdump-3.8.2-9.RHEL4 How reproducible: Always Steps to Reproduce: 1. modprobe ib_ipoib 2. tcpdump -i ib0 3.
