From bd31490718b47d91b0926619635ba967505457e7 Mon Sep 17 00:00:00 2001 From: Wei Fang Date: Wed, 19 Nov 2025 10:51:48 +0800 Subject: [PATCH] net: fec: remove duplicate macros of the BD status There are two sets of macros used to define the status bits of TX and RX BDs, one is the BD_SC_xx macros, the other one is the BD_ENET_xx macros. For the BD_SC_xx macros, only BD_SC_WRAP is used in the driver. But the BD_ENET_xx macros are more widely used in the driver, and they define more bits of the BD status. Therefore, remove the BD_SC_xx macros from now on.
