Hello All,
Recently I started to use IgH EtherCAT Master.
There is a following error in ethernet.c and generic.c. It occurs
when complying with linux kernel > 3.17
error: macro "alloc_netdev" requires 4 arguments, but only 3 given
dev->netdev = alloc_netdev(sizeof(ec_gen_device_t *), &null,
ether_setup);
I made a patch which resolves the problem and would like to share it.
Hope it is useful.
best regards,
Alexey
