The net code is mostly consistent in using 'Packet' rather than 'Pkt', so
rename the minor detractor to follow suite.

The patch fixes the bug of partial initialization of global network
parameters.
Upon u-boot's start up the first ping command causes a failure of the
consequent TFTP command. It happens in the recently added mechanism of
the NetLoop initialization where initialization of global network
parameters is separated in the NetInitLoop routine which is called per
env_id change. Thus, ping request will initialize the network parameters
necessary for ping operation only, afterwards the env_changed_id will be
set to the env_id that will prevent all following initialization requests
from other protocols.
The problem is that the initialized by ping subset of network parameters
is not sufficient for other protocols and particularly for TFTP which
requires the NetServerIp also.

NetLoop polls every cycle with getenv some environment variables.
This is horribly slow, especially when the environment is big.
This patch reads only the environment variables in NetLoop,
when they were changed.
Also moved the init part of the NetLoop function in a seperate
function.

This patch removes volatile from:
volatile IP_t *ip = (IP_t *)xip;
Due to a bug, avr32-gcc will assume that ip is aligned on a word boundary when
using volatile, which causes an exception since xip isn't aligned on a word
boundary.

Enforce millisecond semantics of the first argument to NetSetTimeout() --
the change is transparent for well-behaving boards (CFG_HZ == 1000 and
get_timer() countiing in milliseconds).
Rationale for this patch is to enable millisecond granularity for
network-related timeouts, which is needed for the upcoming automatic
software update feature.
Summary of changes:
- do not scale the first argument to NetSetTimeout() by CFG_HZ
- change timeout values used in the networking code to milliseconds

U-boot can complain a lot about 'checksum bad' when it is attached to the network.
It is annoying for ordinary users who start to doubt the network connection
in general when they see messages like this.
This is caused by the routine NetCksumOk() which cannot handle IP-headers longer
than 20 bytes. Those packages can be ignored anyway by U-boot, so we trash them
now before checking the checksum.

Currently the timeout waiting for an ARP reply is hard set to 5 seconds.
On i.MX31ADS due to a hardware "strangeness" up to four first IP packets
to the boards get lost, which typically are ARP replies. By configuring
the timeout to a lower value we significantly improve the first network
transfer time on this board. The timeout is specified in milliseconds,
later internally it is converted to deciseconds, because it has to be
converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on
different boards.

The purpose of this routine is receiving a single network frame, outside of
U-Boot's NetLoop(). Exporting it to standalone programs that run on top of
U-Boot will let them utilise networking facilities. For sending a raw frame
the already existing eth_send() can be used.
The direct consumer of this routine is the newly introduced API layer for
external applications (enabled with CONFIG_API).

Add ICMP_ECHO_REQUEST packet support by responding with a ICMP_ECHO_REPLY.
This permits the ping command to test the phy interface when the phy
is put in loopback mode (typically by setting register 0 bit 14).
It also allows the port to respond to an external ping when u-boot is
processing some other net command (such as tftp). This is useful when
tftp appears to hang.
