1GBit
devices

Comment (by anonymous):
OK, found the reason for the issue.
Kernel 3.14 introduced an additional reset of the switch in
drivers/net/phy/phy_device.c, function phy_init_hw.
This reset clears the Autoneg flag in the switch.
A quick fix is to change this new reset command.
Change BMCR_RESET to BMCR_RESET | BMCR_ANENABLE
However this might not be the ideal fix.
I raised this topic on the openwrt devel mailing list and hope
that the maintainers of the ar8216 driver can come up with a
suggestion for a proper fix.
