Elastic Network Adapter
With the release of RHEL 7.4, Red Hat updated the kernel-drivers to include support for AWS's Elastic Network Adapter. Red Hat also updated their published AMIs to support this capability.
Previously, when SRIOV-enabling a Red Hat AMI so that the
ixgbevfethtool eth0# ethtool -i eth0 driver: ena version: 1.0.2 firmware-version: expansion-rom-version: bus-info: 0000:00:03.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: no supports-priv-flags: no
However, when trying to query for speed, I just get an error:
# ethtool eth0 Settings for eth0: Cannot get device settings: Operation not permitted Cannot get wake-on-lan settings: Operation not permitted Current message level: 0x000004e3 (1251) drv probe ifup rx_err tx_err tx_done Link detected: yes
Other than, "eth0 is bound to ena so you know the speeds are available", is there any way to probe for the actual NIC-speed?
