Here is the caller graph for this function:

netif_input()

err_t netif_input	(	struct pbuf *	p,
		struct netif *	inp
	)

Forwards a received packet for input processing with ethernet_input() or ip_input() depending on netif flags. Don't call directly, pass to netif_add() and call netif->input(). Only works if the netif driver correctly sets NETIF_FLAG_ETHARP and/or NETIF_FLAG_ETHERNET flag!

netif_issue_reports()

static void netif_issue_reports ( struct netif *  netif, u8_t  report_type  )
