[ Upstream commit 927f42fcc1b4f7d04a2ac5cf02f25612aa8923a4 ]
According to board schematic, PHY provides both, RX and TX delays. However, according to "fix" Realtek provided for this board, only TX delay should be provided by PHY. Tests show that both variants work but TX only PHY delay works slightly better.
Update ethernet node to reflect the fact that PHY provides TX delay.
