* net: Use new checksum functionsSimon Glass2015-02-12-6/+4
| | | | | | | Drop the old checksum functions in favour of the new ones. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
* SPDX License cleanup for LiMon imported filesWolfgang Denk2014-10-10-0/+1
| | | | | | | | | | | | | | | | A number of network related files were imported from the LiMon project; these contain a somewhat unclear license statement: Copyright 1994 - 2000 Neil Russell. (See License) I analyzed the source code of LiMon v1.4.2 which was used for this import. It does not contain any "License" file, but the top level directory contains a file "COPYING", which turns out to be GPL v2 of June 1991. So it is legitimate to conclude that the LiMon derived files are also to be released under GPLv2. Mark them as such. Signed-off-by: Wolfgang Denk <wd@denx.de>
* net: Allow filtering on debug traces in the net subsystemJoe Hershberger2012-05-23-2/+2
| | | | | | | | | | | | 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: Don't copy every packet that waits for an ARPJoe Hershberger2012-05-23-3/+2
| | | | | | | | | 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 Hershberger2012-05-23-7/+3
| | | | | | | | 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 Hershberger2012-05-23-5/+5
| | | | | | | | | 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 protect access to the NetState variableJoe Hershberger2012-05-23-2/+2
| | | | | | | Changes to NetState now go through an accessor function called net_set_state() Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: Refactor to use NetSendPacket instead of eth_send directlyJoe Hershberger2012-05-23-2/+1
| | | | | | | | 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 ping receive handlerJoe Hershberger2012-05-23-16/+2
| | | | | | | | There is no need to call through the handler... inline it Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
* net: Refactor packet length computationsJoe Hershberger2012-05-23-3/+4
| | | | | | | | | 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: Refactor IP, UPD, and ICMP header writing functionsJoe Hershberger2012-05-23-29/+23
| | | | | | | | ICMP (ping) was reimplementing IP header code... it now shares code. 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: Un-typedef ICMP_tJoe Hershberger2012-05-23-1/+1
| | | | | | Remove typedef and lower-case name Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: cosmetic: Un-typedef Ethernet_tJoe Hershberger2012-05-23-1/+1
| | | | | | | 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: Split struct ip_udp_hdr into ip_hdrJoe Hershberger2012-05-23-5/+5
| | | | | | | | Add a structure that only contains IP header fields to be used by functions that don't need UDP Rename IP_HDR_SIZE_NO_UDP to IP_HDR_SIZE Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: cosmetic: Un-typedef IP_tJoe Hershberger2012-05-23-3/+3
| | | | | | | | 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 PING out of net.cJoe Hershberger2012-05-23-0/+140
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>
