From 3b721117fe150fc4d78628d78627f9b446930b44 Mon Sep 17 00:00:00 2001 From: Ethan Nelson-Moore Date: Fri, 23 Jan 2026 19:22:43 -0800 Subject: [PATCH] net: usb: sr9700: replace magic numbers with register bit macros The first byte of the Rx frame is a copy of the Rx status register, so 0x40 corresponds to RSR_MF (meaning the frame is multicast). Replace 0x40 with RSR_MF for clarity. (All other bits of the RSR indicate errors. The fact that the driver ignores these errors will be fixed by a later patch.) The first byte of the status URB is a copy of the NSR, so 0x40 corresponds to NSR_LINKST. Replace 0x40 with NSR_LINKST for clarity.
