Wiesner András ab8d45932f Timestamping and bunch of bugfix and optimization
- Timestamping management added
- Errors due to reading uninitialized data in ARP fixed
- EthInterface reworked, incoming packet notification and payload readout separated (through which fixing concurrent access problems)
- RX and TX offloads added
- Capability to add a packet sieve layer without prior registration of specific packet class added (this makes it possible to register arbitrary EtherType connection blocks, for example)
