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).

Verify checksums on the RX datapath.2007-01-03T20:48:52+00:00Michael Brown2007-01-03T20:48:52+00:00urn:sha1:a0525a4ed36a28260d6dee4723bd6a1eb29020be
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.
