885a630ddf Fix routing when a gateway exists. This should probably be split into
a separate function.

467e9627cc Added features that will be required for PXE UDP support.
Introduced struct sockaddr_tcpip, to simplify code that deals with
both IPv4 and IPv6 addresses.

Reorganised parts of tcpip.c and udp.c.

c24546c70b Minor changes to the network layer rx() functions 2006-08-01 20:27:26 +00:00
Michael Brown
1ebb68e49a Renamed trans_{rx,tx}() to tcpip_{rx,tx}(), since they are specific to
the TCP/IP protocol suite (rather than being general transport-layer
functions).

c9ea710930 Renamed net/interface.c and include/gpxe/interface.h to net/tcpip_if.c and include/gpxe/tcpip_if.h respectively. Made changes in the other files. 2006-06-28 15:43:08 +00:00

35557914e3 Simplify ipv4_tx() by not having a separate "source" variable now that
we are constructing the IP header ourselves.

Formatting fix-ups (80 column limit is mandatory!)

90fbff8f34 added support for processing and transmitting without uIP 2006-06-25 05:16:54 +00:00
Michael Brown
8637834031 Made the temporary buffer part of the TCP senddata() API, to ease the
transition away from uIP.

Prepared ipv4.c for transition away from uIP.

3c8aafa209 Simplify RX data path.
Kill off the static single net device and move to proper dynamic
registration (which we need with the new device model).

Break the (flawed) assumption that all network-layer protocols can use
ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP
protocol using ARP_NET_PROTOCOL() and provide a single method for checking
the existence of a local network-layer address.

592a5a99c8 Moved uIP and tcp.c from proto/ to net/ 2006-04-30 01:16:37 +00:00

bac97eb979 Change semantics of network API so that packet-absorbing calls *always*
take ownership of the packet, rather than doing so only if they return
success.  This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.

Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.

129c6c3968 Network layer now works as a proof of concept 2006-04-28 14:13:50 +00:00
Michael Brown
53f78346bf Network API now allows for multiple network devices (although the
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.
