From 8614b8eb5f465742343a2b16ebc1a980b20e33d0 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Tue, 28 Jun 2022 21:14:03 +0200 Subject: [PATCH] realtek: fix egress port mask on rtl839x The flag to enable the outgoing port mask is in CPU header bit 43, with bit 0 being the leftmost bit of the header. This corresponds to BIT(4) in the third 16-bit value of the header. Correctly set AS_DPM by fixing the off-by-one error.
