[openib-general] tcpdump command issue on IB network

[Woodruff, Robert J]

I am not sure this is a openib issue, but perhaps rather a bug in the
utilities
that assumed the size of a MAC address is 8 bytes. 
 
I am not sure if that is the case with this one, but I know it was
the case in some of the user utilities. If this is the case, then
the utility should be fixed. 
 
my 2 cents,
 
woody

	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
