Hello,
found the problem, just forgot to post here.
The problem was that I didn't check for incoming packets with 
ethernetif_input(). The packet was sent, reply received, but not 
processed, so the ARP entry was left as PENDING until ethernetif_input() 
processed the ARP reply and updated the table to STABLE.

Silly problem, sorry.

Thank You for Your time and support.
