[openib-general] tcpdump command issue on IB network

[Jerome Taylor]

Dear developers and list subscribers,

I ran into the following error message running the Linux tcpdump command
on an Infiniband network.

# tcpdump -i ib0

Tcpdump: ioctl: Value too large for defined data type.

I am running the following configuration:
- RedHat AS-4.0 U2, kernel-2.6.9-22.ELsmp
- Gen2 driver (ib-verb-2.0.1-2.6.9_22.ELsmp; ib-ipoib-2.6.9-22.ELsmp)
- tcpdump-3.9.4-3

Has anyone seen this issue before? Is this an issue with the kernel and
support for the larger IB hardware address?

Regards,
Jerome Taylor
