4.20-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. Signed-off-by: Jose Abreu <[email protected]> Cc: Joao Pinto <[email protected]> Cc: David S.
