Subject: [PATCH net-next v2] net: stmmac: dwmac4: Add ip payload error statistics

From: Minda Chen <[email-masked]>
Date: Mon, 30 Sep 2024 19:02:05 +0800

Add dwmac4 ip payload error statistics, and rename discripter bit macro
because latest version descriptor IPCE bit claims ip checksum error or
l4 segment length error.
