Hello,
I do have a problem setting the IPoIB interface MTU in VmWare 5.5 using the 1.8.2 drivers.
The adaptors i use are MCX354A-FCBT (dual-port IB/VPI adaptors - ConnectX3). They have been flashed with the latest firmware 2.30.8000 recently. The same issue applied when using previous firmware.
I have set the mtu_4k parameter to 1 for the mlx4_core module and restarted several time.
The issue I'm having is when setting the 4092 MTU value for the vSwitch who has the vmnic_ib0 adaptor as uplink, i'm getting the:
"Unable to set MTU to 4092 the following uplinks refused the MTU setting: vmnic_ib0" message.
Could you please explain if there are additional steps required for this? Am I missing something?
Thanks in advance..
