+Subject: [PATCH] net: ethernet: mtk_eth_soc: enable XDP support just for
+ MT7986 SoC
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Disable page_pool/XDP support for MT7621 SoC in order fix a regression
+introduce adding XDP for MT7986 SoC. There is no a real use case for XDP
+on MT7621 since it is a low-end cpu. Moreover this patch reduces the
+memory footprint.
