Clarified packet ownership transfer between a few functions.
...
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.

The prototype for strcasecmp() is apparently in strings.h.

Changed ipv4_dump() to consume only one line.

Corrected bugs in the TCP logic. There might be a few more which need to be taken care of.

Fix routing when a gateway exists. This should probably be split into

a separate function.

Remove unused attribute from __table macros; the tables are no longer
...
static since otherwise gcc4 optimises them away completely. Also, it
really *is* an error if the table start and end are unused, so they
certainly shouldn't be marked with attribute unused.

Make the UDP senddata() methods return a status code.
...
udp_connect() now follows the standard BSD sockets semantics and simply
sets the default address for outgoing packets; it doesn't filter incoming
packets.

a0a872f7f1
Updated PXE UDP implementation to use the new Etherboot UDP API.
...
Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)

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.

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).

We shouldn't need to allocate a TX packet buffer when calling newdata();
...
if the application wants to send data then it will have to use the normal
senddata() mechanism.

Request Etherboot encapsulated options.

Parameter request list is yet another option that ISC dhcpd ignores

Set DHCP_MESSAGE_TYPE option within the main options block. This

Packets without a DHCP_MESSAGE_TYPE option are probably just BOOTP
