- moved most ping state into the Net crate proper, since the smoltcp
implementation assumes a tightly bound set of objects and lifetimes
in its icmp abstraction
- created various convenience abstractions for handling single and
multiple pings, blocking and non-blocking.
- refactored the "net" command to use the new form
Initial testing indicates there are still some bugs (seems to be
with the way we are handling timestamping and doing pong retirement)
but at least we're not getting tons of async callback errors like
we were before, and we're not shuttling obscene amounts of state
using Arc-Mutex between the input and output of the ping operations.
Now that I understand how smoltcp does ping better I have regrets.
The demo example in smoltcp uses a funky macro that was a bit
misleading. I have gotten rid of that but I probably would have made
different decisions in implementing this had I understood the API better.
Anyways. It works, but has some trouble handling the cases of timeouts
sometimes.
not fully working yet, but the architecture is there and it builds.
smoltcp's ping implementation (or at least its demo code) was not
very amenable to splitting into modules, had to recode most of it.
the ipv6 is still a hack.
Multicast/Broadcast is not supported by smoltcp it seems, so those
calls are just unimplemented. But we are able to clone UdpSocket,
for the sick puppies who like to do that sort of thing.
