Your driver implements it in
ecos\packages\devs\eth\[family]\[platform]\current\src\xxx.c
There a macro fills in the function pointer HRDWR_send(), in my case
stdims_eth_send:

ETH_DRV_SC(stdims_eth_sc0,
(void*) &stdims_eth0,
"eth0",
stdims_eth_start,
stdims_eth_stop,
stdims_eth_control,
stdims_eth_can_send,
stdims_eth_send,
stdims_eth_recv,
stdims_eth_deliver,
stdims_eth_poll,
stdims_eth_intvector);
NETDEVTAB_ENTRY(stdims_eth_netdev0,
"stdims_eth0",
stdims_eth_init,
&stdims_eth_sc0);

In the documentation you can read the calling order.
