- 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)
