From 767f4a7ca8041442e033dd919b591d00f6901e03 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 12 Oct 2009 09:26:17 +0000 Subject: mdio: Advertise pause (flow control) settings even if autoneg is off Currently, if pause autoneg is off we do not set either pause advertising flag. If autonegotiation of speed and duplex settings is enabled, there is no way for the link partner to distinguish this from our refusing to use pause frames. We should instead set the advertising flags according to the forced mode so that the link partner can follow our lead. This is consistent with the behaviour of other drivers.
