[lwip-users] low_level_output() question

[beach.dk]

Hi there,

One short/quick question.

 

In the ethernetif.c module the function low_level_output() (or actually the function stored in netif->linkoutput) returns an value of the type err_t.

What happens when this is != ERR_OK?

 

Will lwip try to resend this packet later?

Will this be reported up to the 'sending' functions? (I.e.  tcp_write() and udp_send()  )
