====================
lan78xx: Preparations for PHYlink

This patch set is a second part of the preparatory work for migrating
the lan78xx USB Ethernet driver to the PHYlink framework. During
extensive testing, I observed that resetting the USB adapter can lead to
various read/write errors. While the errors themselves are acceptable,
they generate excessive log messages, resulting in significant log spam.
This set improves error handling to reduce logging noise by addressing
errors directly and returning early when necessary.
