Subject: [PATCH net-next 1/2] r8169:prevent enable hardware tx/rx too early
Date: Tue, 2 Dec 2014 16:48:30 +0800	[thread overview]
Message-ID: <1417510111-3568-2-git-send-email-hau@realtek.com> (raw)
In-Reply-To: <1417510111-3568-1-git-send-email-hau@realtek.com>

For RTL8168G/GU/H/EP and RTL8411B remove enable tx/rx from its own hw_start
function. This will prevent enable tx/rx before complete hardware tx/rx
setting.

Tx/Rx will be enabled in the end of function rtl_hw_start_8168.
