_______________________________________________________
Details:
When using GRUB TCP in "server mode" there is no code to actually initialize
remote mac address for the socket structure. This ends up GRUB sending SYN-ACK
packets on all-zero mac in the socket structure and connection never gets
accepted, since remote party never receives the SYN-ACK.
Since GRUB TCP client resolves remote link address on open, similar code was
added to grub_net_tcp_accept.
