Subject: RXFH manual configuration

Hi Jacob,

I am looking at your patch:
d4ab4286276f ethtool: correctly ensure {GS}CHANNELS doesn't conflict ...

I wonder - if I want to configure the number of channels (ethtool -L),
without being aware to the history of indirection table (manually set or
not), how can I know what is the expected behavior?
I should be able, from userspace, to query the value of
netif_is_rxfh_configured() in order to decide whether the outcome of an
ethtool -L command is correct or not.

Do you know if this indication exists?

Thanks,
Tariq

I mis-spoke earlier, this is set in priv_flags and is thus not shared with userspace. I'm not sure if there is any current way to tell the status.

Thanks,
Jake
