  Hello,

This series adds a workaround for the DP83867 Ethernet PHY to fix packet
errors observed with short cables, when both ends of the link use the
DP83867 Ethernet PHY. This issue is described in Section 3.8 at [0].

Also, for the DP83869 Ethernet PHY which supports both RGMII and MII
modes of operation, support is added to allow switching to MII mode by
configuring the OP_MODE_DECODE Register in Section 9.6.1.65 at [1].

Regards,
Siddharth.
