From 4da0b5a786ca4817c0608881c957f5023b9eb72b Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Tue, 28 Jun 2022 21:15:00 +0200 Subject: [PATCH] realtek: fix egress L2 learning on rtl839x The flag to enable L2 address learning on egress frames is in CPU header bit 40, with bit 0 being the leftmost bit of the header. This corresponds to BIT(7) in the third 16-bit value of the header. Correctly set L2LEARNING by fixing the off-by-one error.
