Subject: [PATCH] net: stmmac: Disable EEE mode earlier in XMIT callback
Git-commit: e2cd682deb231ba6f80524bb84e57e7138261149
Patch-mainline: v5.0-rc6
References: git-fixes
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.
