Summary

Add tso_tcp_flags_mask_first_segment, tso_tcp_flags_mask_middle_segment, and tso_tcp_flags_mask_last_segment sysctl-variables to control the handling of TCP flags during TSO.
This allows to fix the handling appropriate for classical ECN and to configure a handling appropriate for accurate ECN.

As at least two, maybe three different NIC vendors have similar capabilities, wouldn't it make sense to have global, driver independent sysctls?
