Subject: [PATCH v2 1/2] net: ethernet: nb8800: Do not apply TX delay at MAC level

From: Sebastian Frias <[email-masked]>
Date: Fri, 4 Nov 2016 19:18:46 +0100

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.
