Note: in the ping.c fix, commit a36b12f95a29647a06b5459198684fc142482020 "net: Move PING out of net.c" mistakenly carried the ifdef CMD_PING clause from when it was necessary to avoid warnings when it was embedded in net.c.

* net: fix typo in arp clean upMike Frysinger2012-07-10-1/+1
| | | | | | | | | | The clean up patch missed an &, so we end up passing an int rather than a pointer to the sprintf function. arp.c: In function 'ArpReceive': arp.c:197: warning: format '%p' expects type 'void *', but argument 3 has type 'int' Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* net: Allow filtering on debug traces in the net subsystemJoe Hershberger2012-05-23-4/+5
| | | | | | | | | | | | Add several levels of DEBUG prints so that you can limit the noise to the severety of your problem. DEBUG_LL_STATE = Link local state machine changes DEBUG_DEV_PKT = Packets or info directed to the device DEBUG_NET_PKT = Packets on info on the network at large DEBUG_INT_STATE = Internal network state changes Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: Work-around for brain-damaged Cisco equipment with arp-proxyJoe Hershberger2012-05-23-0/+14
| | | | | | | | | | | | | | | | | | Cisco's arp-proxy feature fails to ignore the link-local address range This means that a link-local device on a network with this Cisco equipment will reply to ARP requests for our device (in addition to our reply). If we happen to reply first, the requester's ARP table will be populated with our MAC address, and one packet will be sent to us... shortly following this, the requester will get an ARP reply from the Cisco equipment telling the requester to send packets their way instead of to our device from now on. This work-around detects this link-local condition and will delay replying to the ARP request for 5ms so that the first packet is sent to the Cisco equipment and all following packets are sent to our device.

* net: Separate ArpRequest() into lower-level funcJoe Hershberger2012-05-23-9/+13
| | | | | | | | Link-local support will need to send ARP packets, but needs more fine-grained control over the contents. Split the implementation into 2 parts so link-local can share the code. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: Don't copy every packet that waits for an ARPJoe Hershberger2012-05-23-12/+12
| | | | | | | | | Use the NetArpTxPacket for the ARP packet, not to hold what used to be in NetTxPacket. This saves a copy and makes the code easier to understand. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: Remove static allocation for MAC address in PingSend()Joe Hershberger2012-05-23-4/+5
| | | | | | | | Don't force ARP clients to return the MAC address if they don't care (such as ping) Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Mike Frysinger <vapier@gentoo.org>
* net: Add net_update_ether() to handle ARP and Ping repliesJoe Hershberger2012-05-23-1/+1
| | | | | | | | | When the network is VLAN or SNAP, net_update_ether() will preserve the original Ethernet packet header and simply replace the src and dest MACs and the protocol Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: Refactor to separate the UDP handler from the ARP handlerJoe Hershberger2012-05-23-3/+3
| | | | | | | | | | | Call a built-in dummy if none is registered... don't require protocols to register a handler (eliminating dummies) NetConsole now uses the ARP handler when waiting on arp (instead of needing a #define hack in arp.c) Clear handlers at the end of net loop Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: Refactor to use NetSendPacket instead of eth_send directlyJoe Hershberger2012-05-23-3/+3
| | | | | | | | Use this entry-point consistently across the net/ code Use a static inline function to preserve code size Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: Refactor packet length computationsJoe Hershberger2012-05-23-5/+8
| | | | | | | | | Save the length when it is computed instead of forgetting it and subtracting pointers to figure it out again. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
* net: cosmetic: Replace magic numbers in arp.c with constantsJoe Hershberger2012-05-23-17/+17
| | | | | | Use field names and sizes when accessing ARP packets Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: cosmetic: Rename tmp to reply_ip_addr in arp.cJoe Hershberger2012-05-23-3/+3
| | | | | | | Renamed for clarity Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: cosmetic: Un-typedef ARP_tJoe Hershberger2012-05-23-4/+4
| | | | | | Remove typedef and lower-case letters Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: cosmetic: Un-typedef Ethernet_tJoe Hershberger2012-05-23-2/+2
| | | | | | | Separate the Ethernet header from the 802 header. Base the size constants on the structs. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: cosmetic: Un-typedef IP_tJoe Hershberger2012-05-23-1/+1
| | | | | | | | Rename IP header related things to IP_UDP. The existing definition of IP_t includes UDP header, so name it to accurately describe the structure. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: Move ARP out of net.cJoe Hershberger2012-05-23-0/+213
| | | | | | | | Separate this functionality out of the net.c behemoth Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
