Subject: Re: inconsistency of ethtool feature names for get vs. set

Hi,
3 short comments:

1) This is true also to setting GSO:
ethtool -k enp0s8  | grep generic-segmentation-offload
generic-segmentation-offload: on

ethtool -K enp0s8  generic-segmentation-offload off
ethtool: bad command line argument(s)

and
ethtool -K enp0s8  gso off
works.

and also to setting scatter-gather:
ethtool -k enp0s8  | grep scatter-gather
scatter-gather: off

ethtool -K enp0s8  scatter-gather on
ethtool: bad command line argument(s)

And
ethtool -K enp0s8  sg on
works.

2)
you said:
> ethtool -K eth1  rx-gro on

You can also use:
ethtool -K eth1  gro on


3)
>same problem for rx checksum which is displayed as "rx-checksumming" >by the get (-k)
>but need to be "rx-checksum" for the set (-K) directive.
You can also use:
ethtool -K eth1  rx on
or
ethtool -K eth1  rx off

The same for tx-checksum:
ethtool -K eth1  tx on
or
ethtool -K eth1  tx off
