It turns out that when busybox invokes openssl for
IPv4, it does not pass a servername field.
In this case, start amending arguments after '-verify' instead, to catch
the verify_ip argument correctly.
The busybox wget invocation of openssl is broken.
Override by stubbing it out to let openssl pick the verify
hostname instead of wget specified one, which is incorrect.
It may happen that the first pass at nics misses
a viable network interface due to slow link up
or slow spanning tree forwarding.
Repeat the loop through the interfaces to have follow
up chances at success.
