From 0448f90a404a332052aacd45e8445c9fd22cfc61 Mon Sep 17 00:00:00 2001 From: Chengwen Feng Date: Fri, 18 Oct 2024 14:19:38 +0800 Subject: [PATCH] net/hns3: restrict tunnel flow rule to one header [ upstream commit 8887c207b9373a1875031c5346706f698322d66d ] The device's flow director supports a maximum of one tunnel header, if passed more than one tunnel header from rte-flow API, the driver should return error.
