When sending to a multicast address, it may be necessary to specify
the source address explicitly, since the multicast destination address
does not provide enough information to deduce the source address via
the miniroute table.
Allow the source address specified via the data-xfer metadata to be
passed down through the TCP/IP stack to the IPv4 layer, which can use
it as a default source address.

device.
Clear routing table entries before re-attempting DHCP.
Add "name" field to struct device to allow human-readable hardware device2007-01-10T04:22:09+00:00Michael Brown2007-01-10T04:22:09+00:00urn:sha1:dad52745227fd06090e73ea535e0b0fe0f667c60
names.
Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.
Force natural alignment of data types in __table() macros. This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).

Simplify checksum generation on the TX datapath.
We don't actually have a stdio.h header file. Our printf() functions are2006-09-27T10:58:14+00:00Michael Brown2006-09-27T10:58:14+00:00urn:sha1:88e38fa1483891f273f063f92ef71a5c33fe5406
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.
added stdio.h to includes for DBG compilation2006-09-27T05:57:06+00:00Marty Connor2006-09-27T05:57:06+00:00urn:sha1:6ac78f6aff85b2a41d1c98011c41f622d569076aClarified packet ownership transfer between a few functions.2006-08-09T01:24:32+00:00Michael Brown2006-08-09T01:24:32+00:00urn:sha1:a3d508b648906fb742e5205bcd4b97fbf88ea653
Added a large number of missing calls to free_pkb(). In the case of UDP,
no received packets were ever freed, which lead to memory exhaustion
remarkably quickly once pxelinux started up.
In general, any function with _rx() in its name which accepts a pk_buff
*must* either call free_pkb() or pass the pkb to another _rx() function
(e.g. the next layer up the stack). Since the UDP (and TCP) layers don't
pass packet buffers up to the higher-layer protocols (the
"applications"), they must free the packet buffer after calling the
application's newdata() method.
Added features that will be required for PXE UDP support.2006-08-02T00:02:21+00:00Michael Brown2006-08-02T00:02:21+00:00urn:sha1:467e9627ccf0a46c7f077795f0aecff14858718e
Introduced struct sockaddr_tcpip, to simplify code that deals with
both IPv4 and IPv6 addresses.
Reorganised parts of tcpip.c and udp.c.
