at803x: Address packet drops at low traffic rate due to SmartEEE feature
* According to the AR8035 datasheet, smartEEE mode (active by default)
makes the PHY enters sleep after a configurable idle time. It does
this autonomously, without LPI (Low Power Idle) signals coming from MAC.
* Tested with ping (default of 1 second interval) over back-to-back
RGMII between 2 boards having AR8035 at both ends:
- Without patch:
225 packets transmitted, 145 received, 35% packet loss, time 229334ms
- With patch:
144 packets transmitted, 144 received, 0% packet loss, time 146378ms
