Yes I used fconfig to set it (I've attached the current parameters below).
Curiously, it seems that init_all_network_interfaces doesn't take into
account the setup of the "ethernet station address" done with
ecos configuration tool (see hw_addr value in the second attachment)
either under RAM or ROM startup modes.

If the MAC address should not be set for the ip stack to work properly,
do you know how I can unset it?

I've just done the test  with CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_COMMS
macro enabled under RAM startup mode, and ping_test runs just fine.
