[openib-general] Problem configuring ipath_ether

[Matt Leininger]

I have the ipath driver up, running, and working with IPoIB.  I'm using
2.6.16 with svn 5938.  The ipath_ether comes up as eth2.  I can set the
netmask and broadcast, but when I try to set the ip address for this
device I get the following error:


[root at opt1 infiniband]# ifconfig eth2 10.128.20.103
SIOCSIFFLAGS: Operation not permitted


Here is the same command with an strace.


[root at opt1 infiniband]# strace ifconfig eth2 10.128.20.103
