Revision 25382b991d252aed961cd434176240f9de6bb15f authored by Doug Berger on 16 October 2019, 23:06:32 UTC, committed by David S. Miller on 18 October 2019, 17:00:07 UTC
The EPHY integrated into the 40nm Set-Top Box devices can falsely
detect energy when connected to a disabled peer interface. When the
peer interface is enabled the EPHY will detect and report the link
as active, but on occasion may get into a state where it is not
able to exchange data with the connected GENET MAC. This issue has
not been observed when the link parameters are auto-negotiated;
however, it has been observed with a manually configured link.
It has been empirically determined that issuing a soft reset to the
EPHY when energy is detected prevents it from getting into this bad
state.
