hi
One more query
fc_fcoe_send calls *sendmsg(fcoe->fc_fd, &msg, 0) *to send fcoe frame
here fd (ethernet file descriptor) has been initialised in
fc_fcoe_create using function *sa_packet_open* which uses *socket* system
call .
What does this system call do?

In gPXE we have netdev_tx which transfers the iob over the ethernet using
structure 'netdev' which holds our network device
,can we use this in place of socket?


Thank you
