Your patch has been applied to the master branch.
Tested with t_client test, one binary with --enable-iproute2, one without.
"Route add"-Diffs look nicely different, including the /128 bypass...

.. but the resulting output of "ip route" + "ip -6 route" is exactly
the same. Well done :-)
OTOH... :-) - looking at all the changes needed to transport &c->net_ctx,
I wonder why you didn't just hide it in c->c1.tuntap, as we did for the
windows socket... (tt->options.msg_channel). Almost everything related
to "routing and ifconfig" needs to have the tt pointer available already
today...
Warts:
+#else
+ const char *iface;
+ int metric;
+#endif
.. I think this really should be inside the #ifdef TARGET_LINUX block,
not outside in an #else for an #if !defined(TARGET_LINUX)... so the
code further down would then become
#if defined(TARGET_LINUX)
const char *ifcace = NULL;
if (is_on_link(...))
.. having declaration and initialization in one place, and "where it
belongs". Same thing for add_route_ipv6()...
+#if defined(TARGET_LINUX)
+ int metric;
+#endif
.. this is adding an extra #ifdef and taking 3 extra lines instead of
just having "int metric = -1;" down where it's initialized.
delete_route() sports this beauty...
+#if !defined(TARGET_LINUX)
const char *network;
#if !defined(ENABLE_IPROUTE) && !defined(TARGET_AIX)
const char *netmask;
#endif
#if !defined(TARGET_LINUX) && !defined(TARGET_ANDROID)
const char *gateway;
+#endif
.. so you have two linux-specific defines (ENABLE_IPROUTE and TARGET_LINUX)
*inside* an "#if !defined(TARGET_LINUX)"... plus the "metric" thing...
