Subject: [PATCH net-next 4/6] ethtool: link up ethnl_header_policy as a nested policy

From: Jakub Kicinski <[email-masked]>
Date: Mon, 5 Oct 2020 08:57:51 -0700

To get the most out of parsing by the core, and to allow dumping
full policies we need to specify which policy applies to nested
attrs. For headers it's ethnl_header_policy.

$ sed -i 's@\(ETHTOOL_A_.*HEADER\].*=\) { .type = NLA_NESTED },@\1\n\t\tNLA_POLICY_NESTED(ethnl_header_policy),@' net/ethtool/*
