Subject: [PATCH 1/2] net: ethernet: nb8800: Do not apply TX delay at MAC level
Date: Fri, 4 Nov 2016 16:02:24 +0100 [thread overview]
Message-ID: <581CA300.1060609@laposte.net> (raw)
The delay can be applied at PHY or MAC level, but since
PHY drivers will apply the delay at PHY level when using
one of the "internal delay" declinations of RGMII mode
(like PHY_INTERFACE_MODE_RGMII_TXID), applying it again
at MAC level causes issues.
