[U-Boot] [PATCH v3 017/108] RFC: sandbox: net: Suppress the MAC-address warnings
Simon Glass

Mon Oct 21 03:31:50 UTC 2019
These warnings appear every thing sandbox is run (see below) and dwarf the
actual useful output. Suppress them in two ways:
1. For the mismatch warnings, only set the eth<x>addr environment
variables when running tests.
2. For the 'MAC address from ROM' warning, never print this on sandbox.

Unfortunately this breaks the tests so is not applicable as is:
