Subject: [PATCH net-next 0/2] net: support extack in dump and simplify ethtool uAPI

Ethtool currently requires header nest to be always present even if
it doesn't have to carry any attr for a given request. This inflicts
unnecessary pain on the users.

What makes it worse is that extack was not working in dump's ->start()
callback. Address both of those issues.

Jakub Kicinski (2):
  netlink: support extack in dump ->start()
  net: ethtool: don't require empty header nests
