+Subject: [PATCH] net: ethernet: mtk_eth_soc: Avoid truncating allocation
+
+There doesn't appear to be a reason to truncate the allocation used for
+flow_info, so do a full allocation and remove the unused empty struct.
+GCC does not like having a reference to an object that has been
+partially allocated, as bounds checking may become impossible when
+such an object is passed to other code. Seen with GCC 13:
+
+../drivers/net/ethernet/mediatek/mtk_ppe.c: In function 'mtk_foe_entry_commit_subflow':
+../drivers/net/ethernet/mediatek/mtk_ppe.c:623:18: warning: array subscript 'struct mtk_flow_entry[0]' is partly outside array bounds of 'unsigned char[48]' [-Warray-bounds=]
+ 623 | flow_info->l2_data.base_flow = entry;

+Subject: [PATCH] net: mediatek: sgmii: ensure the SGMII PHY is powered down on
+ configuration
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The code expect the PHY to be in power down which is only true after reset.
+Allow changes of the SGMII parameters more than once.
+
+Only power down when reconfiguring to avoid bouncing the link when there's
+no reason to - based on code from Russell King.
+
+There are cases when the SGMII_PHYA_PWD register contains 0x9 which
+prevents SGMII from working. The SGMII still shows link but no traffic
+can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
+taken from a good working state of the SGMII interface.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: fix RX data corruption issue
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Also set bit 12 when setting up MAC MCR, as MediaTek SDK did the same
+change stating:
+"If without this patch, kernel might receive invalid packets that are
+corrupted by GMAC."[1]
+This fixes issues with <= 1G speed where we could previously observe
+about 30% packet loss while the bad packet counter was increasing.
+Unfortunately the meaning of bit 12 is not documented anywhere in SDK
+code or datasheets.
