Then touch more lines of source - the patch as it is is unreadable.

>- The partial reset fix (again, to the best of my knowledge) is only needed when the internal PHY being used has reset, but the MAC has not.  The dspcfg != np->dspcfg test identifies an internal PHY that has been reset, and triggers the driver to do a a complete MAC/PHY reset.  When using an external PHY, the test continually causes unneeded resets.  The change to set np->dspcfg to 0 prevents it.  This was the minimal change to get the desired results.

Again, miminal change doesn't matter. Add a

+ if (dev->if_port != PORT_TP) return;

into {do,undo}_cable_magic() and netdev_timer(). Perhaps with a comment 
that the following block is specific to the internal PHY.
