Hi all, we are doing a project on IBM x-blades using Mellanox/RoCE. I have some difficulties to get RoCE based VLANs to run. We are currently on Linux 3.8. No OFED material involved. While non-VLAN devices work ok, i experience the following on VLAN devs - a GID for the VLAN is created and we use the proper index for gid source addr. - a ping on the VLAN-device runs ok - rdma/roce traffic fails in that the sender overruns the send retry count.
In terms of Mellanox driver level, what gives us Linux 3.8? Are we at most current driver level? And do we have to take special setup for VLAN, i.e. special MLX4 module parms, or special qp parameters to get this going? Any help on this is very much appreciated.
