Subject: [RFC PATCH net-next 6/9] net/sched: cls_flower: add tunnel flags to fl_{set,dump}_key_flags()
Date: Tue, 11 Jun 2024 23:53:39 +0000
Message-ID: <20240611235355.177667-7-ast@fiberby.net>
In-Reply-To: <20240611235355.177667-1-ast@fiberby.net>

Prepare to set and dump the tunnel flags.

This code won't see any of these flags yet, as these flags
aren't allowed by the NLA_POLICY_MASK, and the functions
doesn't get called with encap set to true yet.
