[PATCH AUTOSEL 4.14 14/36] net: stmmac: Disable EEE mode earlier in XMIT callback

[Sasha Levin <sashal@kernel.org>]

From: Jose Abreu <jose.abreu@synopsys.com>

[ Upstream commit e2cd682deb231ba6f80524bb84e57e7138261149 ]

In stmmac xmit callback we use a different flow for TSO packets but TSO
xmit callback is not disabling the EEE mode.

Fix this by disabling earlier the EEE mode, i.e. before calling the TSO
xmit callback.
