Overview
SPDX-License-Identifier: Apache-2.0 Definition: interface::ring
Sets interface ring parameters (with ethtool)
Parameters:
-
$interface: The network interface to operate on
-
$setting: The ring to resize (tx, rx, rx-mini, rx-jumbo)
-
$value: The new ring size
Note this doesn't check/set at runtime, because at least with
some drivers that restarts the interface and causes some traffic loss
