[U-Boot] [PATCH v2] net: asix: add support for AX88772B

[Marek Vasut <marek.vasut@gmail.com>]

Dear Lucas Stach,

> There are multiple changes needed to make AX88772B work:
> 
> 1. add vendor and product ID (trivial)
> 
> 2. We need to read out the MAC address from the EEPROM and write
> it into the NodeID register manually.
> 
> 3. The packet length check has to be adjusted, as all ASIX chips
> only use 11 bits to indicate the length. AX88772B uses the other
> bits to indicate unrelated things, which cause the check to fail.
> This fix is based on a fix for the Linux kernel by Marek Vasut.
> Linux upstream commit: bca0beb9363f8487ac902931a50eb00180a2d14a
> 
> 4. AX88772B provides several bulk endpoints. Only the first
> IN/OUT endpoints work in the default configuration. So stop
> enumeration after we found them to avoid overwriting the
> endpoint config with a non-working one.
> 
> This was tested to work on a Colibri T20 board.
> Patch is based on u-boot-net/next.
> 
> v2:
> - split out eeprom mac load into separate function
> - add flags to driver to get a clean way to enable workarounds
>   or special functions
[...]

Quick review looks fine to me, Joe?
