VxLAN offloading is not functional if the NIC is running in multichannel mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole connectivity through the NIC and the device needs to be down and up to restore it. The firmware should take care about it and does not allow the conversion of interface to tunnel type (be_cmd_manage_iface) or should support VxLAN offloading if multichannel config is enabled. I have tested this on the latest available firmware (10.6.144.21).
