beed9726e3 remove unreferenced macros...
These were previously used while trying to parse out specific headers.  They are no longer required though because the current length bounds checks covers edge cases.

This to allow configurable time between knock sequence transmissions.  It's important the sequence arrive in the correct order, and some networks have multiple paths.

All checks were successful
continuous-integration/drone/push Build is passing
This provides another layer of additional protection against sweep attacks by ensuring the correct sequence be entered rapidly, within 3 seconds by default.  It also prevents a client from sitting stuck forever part way through an old knock sequence.

3ae568639e add flag to specify alternative filepath to secret
For the hyp client to be able to support multiple servers, each with their own secret, this capability is requried.

ead7578544 change pcap snaplen to 126 bytes
We really only care getting as far as the UDP header and can discard the rest.  This should reduce load, and perhaps enable full pcap with ports on the BPF filter

UDP header = 8 bytes
IPv4 max size = 60 bytes
IPv6 fixed size = 40 bytes
Ethernet header size = 18 bytes

291cbaabd4 BREAKING: changes to CLI interface, moved to cobra CLI
To better support configuration and user friendliness, migrated to cobra based CLI.  The source tree structure has also changed to single go module, the server has been renamed hypd and client has been named hyp.  The original structure came into being organically, but now that the vision is more complete it's best to make these adjustments now.

bd7fff97b3 rename hyp-client to hyp and upgrade internal dependencies
hyp-client is cumbersome.  The server is called hypd, so it's fine if the client is just called hyp.  Not only is it fine, it's better.
