As I do not know off-hand, how does this compare with other commands
which can be used to set a variable? I assume it's similar. And then,
oh, we don't have doc/cmd/usage/dns.rst to start with. So, follow-up to
this series please, document the network commands that we have in both
lwip and legacy stack and please note where there's differences if any.
Thanks!
