Message-ID: <1476685548-15574-1-git-send-email-niklass@axis.com> Date: Mon, 17 Oct 2016 08:25:48 +0200 From: Niklas Cassel <niklas.cassel@...s.com> To: <larper@...s.com>, <netdev@...r.kernel.org> CC: <linux-kernel@...r.kernel.org>, Niklas Cassel <niklass@...s.com> Subject: [PATCH 1/2] dwc_eth_qos: do not clear pause flags from phy_device->supported From: Niklas Cassel <niklas.cassel@...s.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).
