[PATCH net-next 04/10] net: stmmac: always enable channel TSO when supported

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Rather than configuring the channels depending on whether GSO/TSO is
currently enabled by the user, always enable if the hardware has
TSO support and the platform wants TSO to be enabled.

This avoids TSO being disabled on a channel over a suspend/resume
when the user has disabled TSO features, and then the hardware
misbehaves when TSO is re-enabled.
