Subject: [PATCH 00/11] selftests: Improve nettest and net/fcnal-test.sh

This is a series of improvements to nettest and fcnal-test.sh from
tools/testing/selftests/net which make tests run faster. For me this
reduces the runtime from ~40minutes to ~5minutes and makes the tcp
tests very fast.

Some of the early commits are outright bugfixes.

The tests DO NOT pass perfectly for me on latest net-next/master but I
verified that the failures also happen without my changes. Here is the
list of failures:

TEST: ping local, VRF bind - VRF IP                                           [FAIL]
TEST: Raw socket bind to local address - VRF IP                               [FAIL]
TEST: ping out, VRF bind - ns-B IPv6 LLA                                      [FAIL]
TEST: ping out, VRF bind - multicast IP                                       [FAIL]
TEST: TCP socket bind to out of scope local address - ns-A loopback IPv6      [FAIL]
TEST: TCP socket bind to VRF address with device bind - VRF IPv6              [FAIL]

Three of those were not tested by default before my changes, only with
explicit -t 'bind bind6'

This is related to my work on TCP-AO but there are no patch
dependencies
