ena
— Driver for
the AWS Elastic Network Adapter
/dev/net/ena*
The ena driver is a GLDv3 NIC driver for the AWS Elastic Network Adapter family of virtual devices. The driver supports:
By design, this driver does not support VNICs. A given ENA device can only ever receive traffic for a single unicast MAC address and IP address combination, as determined by the AWS configuration. There is no support for promiscuous mode, or for receiving traffic for additional unicast or multicast addresses.
The ena.conf file contains user configurable parameters, each of which is described below. This file is read when an ENA device is found and an instance of the driver is attached to it. Changes made to this file do not affect running instances. Only instances attached after the changes will see the effects of those changes. Therefore, if you want your change to take effect on a running instance, you must somehow reload it. That could be done by a manual reloading of the driver or a system reboot.
The configuration file can be found at /kernel/drv/ena.conf.
The tunables in ena.conf are considered Evolving and may change in the future.
