The recent GRE selftests defined NUM_NETIFS=10. If the users copy
forwarding.config.sample to forwarding.config directly, they will get
error "Command line is not complete" when run the GRE tests, because
create_netif_veth() failed with no interface name defined.
Fix it by extending the NETIFS with p9 and p10.

Commit bdb7cc643f ("ipv6: Count interface receive statistics on the
ingress netdev") does not work when ip6_forward() executes on the skbs
with vrf-enslaved netdev. Use IP6CB(skb)->iif to get to the right one.
Add a selftest script to verify.

Add TC_FLAG value to tests topology.
This flag supposed to be skip_sw/skip_hw which means do not filter by
software/hardware.
This can be useful for adding tests to forwarding directory, and be able
to verify that packets go through the hardware.
When the flag is not set or set to 'skip_hw', tests can still be executed
with veth pairs.

Add NETIF_NO_CABLE port to tests topology.
The port can also be declared as an environment variable and tests can be
run like that:
NETIF_NO_CABLE=eth9 ./test.sh eth{1..8}
The NETIF_NO_CABLE port will be used by ethtool_extended_state test.

The current timeout (2 seconds) proved to be too low for some (emulated)
systems where we run the tests.
Make the timeout configurable and default to 5 seconds.

Some users want to be able to run the tests without a configuration file
which is useful when one needs to test both virtual and physical
interfaces on the same machine.
Move the defines that set the type of interface to create and whether to
create it away from the optional configuration file to the library like
the rest of the defines.

For tests using veth interfaces, the test infrastructure can create
the netdevs if they do not exist. Arguably this is a preferred approach
since the tests require p$N and p$(N+1) to be pairs.
