Hi again,
I just noticed a function called ethernet_input(). Weird, haven't noticed that
before.
Anyways, the contents of that function answers my first question.
But:
Has there been made crucial updates to the lwip core files, since the lwip
1.3.0 stable version was released ?If yes, does these changes affect me ?
best regards,
Martin
From: [EMAIL PROTECTED]: [EMAIL PROTECTED]: [lwip-users] lwip 1.3.0-stable,
handling input in ethernetif_input()Date: Thu, 20 Nov 2008 08:54:00 +0100
Hi list, I am using lwip 1.3.0-stable, I am using the Netconn API.Through lwip
i run a webserver and a server client.In lwip i use the following: - TCP- DHCP-
ARP- UDP (DHCP) I have through the last two days, reviewed my port files,
ethernetif.c and sys_arch.c. Which led to small changes in the code, which
resulted in greaterstability. However, i have seen two different
implementations of ethernetif_input(),where the input is handled differently
(see below), but both seem to work. So my questions are:1. Are both
implementations of the ethernetif_input(), valid ? (see code below)2. Has there
been made crucial updates to the lwip core files, since the lwip 1.3.0 stable
version was released ?2.a If yes, does these changes affect me ?1.
(ETHARP_TRUST_IP_MAC is defined in lwipopts.h)static voidethernetif_input( void
* pvParameters ){....switch( htons( ethhdr->type ) ) { // IP packet? case
ETHTYPE_IP: // pass to network layer if (xNetIf->input( p, xNetIf ) !=
ERR_OK) { pbuf_free( p ); p = NULL; } break; case ETHTYPE_ARP: #if
ETHARP_TRUST_IP_MAC // update ARP table etharp_ip_input( xNetIf, p );#endif
// pass p to ARP module etharp_arp_input( xNetIf, ethernetif->ethaddr, p );
break; default: pbuf_free( p ); p = NULL; break; }} 2.static
voidethernetif_input( void * pvParameters ){.... switch( htons( ethhdr->type )
) { // IP packet? case ETHTYPE_IP: // update ARP table
etharp_ip_input( xNetIf, p ); // skip Ethernet header pbuf_header( p,
(s16_t)-sizeof(struct eth_hdr) ); // pass to network layer if
(xNetIf->input( p, xNetIf ) != ERR_OK) { pbuf_free( p ); p = NULL;
} break; case ETHTYPE_ARP: // pass p to ARP module
etharp_arp_input( xNetIf, ethernetif->ethaddr, p ); break; default:
pbuf_free( p ); p = NULL; break; }} best regards,Martin
