From 6db31942e3470607be155d2c641c7a15da3c826c Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sun, 30 Nov 2025 15:16:50 +0200 Subject: [PATCH] net: dsa: realtek: use simple HSR offload helpers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit All known Realtek protocols: "rtl4a", "rtl8_4" and "rtl8_4t" use dsa_xmit_port_mask(), so they are compatible with accelerating TX packet duplication for HSR rings. Enable that feature by setting the port_hsr_join() and port_hsr_leave() operations to the simple helpers provided by DSA.
