gso_test_tcp_resegment() is a v1 leftover, when tcp_gso_segment() needed a
max_segs exception in its "untrusted source" check.  max_segs is passed
through now, so it is unnecessary and can be dropped in v5.

gso_test_tcp_limit_l3_proto() was added in v3 for the L3 protocol limit
lookup fix (1/5).

gso_test_tcp_resegment_l3_len() was added in v3 for the 64 KiB cap on the
grouped output (4/5), from this sashiko report on v2:

You are right that they are verbose and one-off.  I do not have a concrete plan
yet: I will try to trim them, or just drop them and add a selftest later.  Any
suggestions?
