Subject: net: stmmac: Disable EEE mode earlier in XMIT callback
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e2cd682deb231ba6f80524bb84e57e7138261149;p=android-x86%2Fkernel.git

net: stmmac: Disable EEE mode earlier in XMIT callback

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.
