r8169: disable tx interrupt coalescing on RTL8168
In contrast to switching rx irq coalescing off what fixed an issue,
switching tx irq coalescing off is merely a latency optimization,
therefore net-next. As part of this change:
- Remove INTT_0 .. INTT_3 constants, they aren't used.
- Remove comment in rtl_hw_start_8169(), we now have a detailed
description by the code in rtl_set_coalesce().
- Due to switching irq coalescing off per default we don't need the
initialization in rtl_hw_start_8168(). If ethtool is used to switch
on coalescing then rtl_set_coalesce() will configure this register.
For the sake of completeness: This patch just changes the default.
Users still have the option to configure irq coalescing via ethtool.
