You can use netlink to get them all

ctxs = cfg.ethnl.rss_get({}, dump=True)  

Jakub, maybe it's a rookie question but I am having trouble getting
the netlink call to work.
Not sure if my analysis is right but it looks like I don't have the
right schema..
It appears like the decode does not ignore unsupported ethnl options?
I always get the error:

# Error decoding 'input-xfrm' from 'rss'

with the below call stack:

Do you think I am missing some config?

Ah! I think you run into what I recently fixed in net.
Could you try with 1c172febdf065375 cherry-picked to your tree?
It's sitting in net, hasn't reached net-next yet.
Sorry about that..
