Summary0005139: Ethernet controller does not work
DescriptionPower Supply:
L21 must be changed with 0R (0805) [RTL8211FD is an LDO variant. No need for an inductor]

C109, R108, R111 must be removed from the design. (no need for a voltage divider)
R109 should be changed with 0R resistor.

Config Jumpers:
Config Jumper names must be corrected. (Pins and their functionality)
R215 must have been connected to 3V3. [in order to set the NVCC_RGMII as 1V8]

LED Logic:
LED pins which have pull-downs (LINK10n & ACTLED) must be driven with an NMOS in order the invert the logic. (otherwise they are always on)
