netX90/4000: IO data is produced into wrong multicast group/multicast MAC and multicast IP inconsistent

I/O communication in T->O direction transport type "Multicast" will start, but since we produce for a corrupted destination MAC address, connection will timeout immediately.

This is due to a bug in LWIP, so this external component has to be fixed and updated.
Note that this problem will be shadowed if your network interface is in promisc mode (i.e. if Wireshark is running and your Connection originator is a PC/Software Scanner)

Only observed on netX90/4000 due to different toolchain/compiler with harder optimization techniques.
