Vladimir, what's the progress of the patch from Mellanox? Deadline for 6.1 update inclusion is closing... Do you have some ETA we can work with?

Comment 13 Jan Stodola 2011-04-27 16:08:11 UTC 
Tested on build RHEL6.1-20110420.0:
[root@rdma3 ~]# rpm -qa | grep dhc
dhclient-4.1.1-19.P1.el6.x86_64
dhcp-4.1.1-19.P1.el6.x86_64

Testing environment: Two machines connected to an IB switch, the first one configured as a DHCP server listening on ib0 interface, the second one was a DHCP client.

[root@rdma3 ~]# lspci | grep InfiniBand
0c:00.0 InfiniBand: QLogic, Corp. IBA6120 InfiniBand HCA (rev 02)
0e:00.0 InfiniBand: QLogic, Corp. IBA6120 InfiniBand HCA (rev 02)

After running "dhclient ib0" on the client machine, an IP address from the server was received and network interface ib0 was set based on the server configuration, I was able to login via ssh from the server to the client and vice-versa.

Moving to VERIFIED.
