According to AM335x TRM[1] 14.3.6.2, AM437x TRM[2] 15.3.6.2 and DRA7 TRM[3] 24.11.4.8.7.3.3, in-band mode in EXT_EN(bit18) register is only available when PHY is configured in RGMII mode with 10Mbps speed. It will cause some networking issues without RGMII mode, such as carrier sense errors and low throughput. TI also mentioned this issue in their forum[4]. This patch adds the check mechanism for PHY interface with RGMII interface type, the in-band mode can only be set in RGMII mode with 10Mbps speed.
