This repository contains my work regarding r8169 linux driver. Actual source code is C&P from original r8169.c file and cleaned from redundant logic. Motivation was preparing minimal driver (in sense of source code) which:

• works with real PCIe device RTL8111/8168
• handle probe() procedure via insmod
• handle open() procedure
• handle close() procedure
• handle remove() procedure via rmmod
• perform full autonegotiation with link partner
• handle events related to link state (plugging cable trigger LOWER_UP + Link Up)
• setup interface to LOWER_UP state

Because final driver is quite big, fragile and ugly I decided to extract each iteration to separated files: r8169.0.c, r8169.1.c etc.
