[PATCH 4.19 090/149] net: stmmac: Disable EEE mode earlier in XMIT callback

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ 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.
