[etherlab-users] Newbie: EtherCAT Master 1.5.2 with Ubuntu - modules installation problem

[Ravi Shankar]

Hi Jakub,

  I was able to resolve sock_create_kern by changing it to:

ret = sock_create_kern(&init_net, PF_PACKET, SOCK_RAW,
htons(ETH_P_ETHERCAT),

            &dev->socket);

 Not sure if this will fix your issue.

Thanks
