Subject: [PATCH net] net: stmmac: fix ethtool flow control not able to get/set
Date: Tue, 21 May 2019 12:55:42 +0800	[thread overview]
Message-ID: <1558414542-28550-1-git-send-email-weifeng.voon@intel.com> (raw)

From: "Tan, Tee Min" <tee.min.tan@intel.com>

Currently ethtool was not able to get/set the flow control due to a
missing "!". It will always return -EOPNOTSUPP even the device is
flow control supported.

This patch fixes the condition check for ethtool flow control get/set
function for ETHTOOL_LINK_MODE_Asym_Pause_BIT.

Fixes: 3c1bcc8614db (“net: ethernet: Convert phydev advertize and supported from u32 to link mode”)
