The default packet steering behavior can be configured via the parameter default_ps in the global section; the default value is true to keep backwards compatibility. Device packet steering (rps/xps) config can still be used to override the default behavior. This allows you to disable packet steering for all devices without the need to define a device config list which disables receive/transmit packet steering Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> --- config.c | 6 ++++++ device.c | 56 +++++++++++++++++++++++++++++++++++++++++++++++++------- device.h | 3 +++ 3 files changed, 58 insertions(+), 7 deletions(-)
