Subject: [PATCH net-next 4/6] net: stmmac: move initialisation of
 priv->tx_lpi_timer to stmmac_open()

The initialisation of priv->tx_lpi_timer only happens once during the
lifetime of the driver, which is during the initial administrative
open of the device. Move this initialisation out of __stmmac_open()
into stmmac_open().
