Re: [PATCH] sbc8641: drop bogus PHY IRQ entries from DTS file

This file was originally cloned off of the MPC8641D-HPCN reference

this board does not.  The bogus entry was largely inert and went
undetected until commit 321beec5047af83db90c88114b7e664b156f49fe
("net: phy: Use interrupts when available in NOLINK state") was
added to the tree.

With the above commit, the board fails to NFS boot since it sits
waiting for a PHY IRQ event that of course never arrives.  Removing
the bogus entries from the DTS file fixes the issue.

Hi Paul

Originally the interrupt is used for detecting the link has gone
down. That would of also been bogus before. Have you tried this?  If
that is also broken, maybe you need to add a fixes: tag so that it
gets back ported?
