Subject: [PATCH net-next v2 2/3] tools: ynl-gen: use macro for binary min-len check
Date: Tue,  2 Sep 2025 15:46:36 +0000	[thread overview]
Message-ID: <20250902154640.759815-3-ast@fiberby.net> (raw)
In-Reply-To: <20250902154640.759815-1-ast@fiberby.net>

This patch changes the generated min-len check for binary
attributes to use the NLA_POLICY_MIN_LEN() macro, thereby the
generated code supports strict policy validation.

With this change TypeBinary will always generate a NLA_BINARY
attribute policy.

This doesn't change any currently generated code, as it isn't
used in any specs currently used for generating code.
