| |
From: Niklas Cassel <niklas.cassel@axis.com>
phy_device->supported is originally set by the PHY driver. The ethernet driver should filter phy_device->supported to only contain flags supported by the IP. The IP supports setting rx and tx flow control independently, therefore SUPPORTED_Pause and SUPPORTED_Asym_Pause should not be cleared. If the flags are cleared, pause frames cannot be enabled (even if they are supported by the PHY).
