We can now successfully boot EFI applications from disk, but users
may want to also run them from a PXE setup.
This patch implements rudimentary network support, allowing a payload
to send and receive network packets.
With this patch, I was able to successfully run grub2 with network
access inside of QEMU's -M xlnx-ep108.

TFTP source and destination port variable names are
'tftpsrcp' and 'tftpdstp' in the code, but 'tftpsrcport'
and 'tftpdstport' in the README file. Fix the README.
Add environment variable 'tftptimeoutcountmax'. As per the
comments about the global variable tftp_timeout_count_max,
make sure tftptimeoutcountmax is nonnegative.
Introduce configuration option CONFIG_NET_TFTP_VARS,
which controls whether environment variables tftpblocksize,
tftptimeout, and tftptimoueoutcountmax are read by the TFTP
client code. CONFIG_NET_TFTP_VARS defaults to y but can be
set to n by targets with to tight size contraints.
Make bf527-ezkit set CONFIG_NET_TFTP_VARS to n to keep the
target size below limit.

Commit 620776d "tftp: adjust settings to be suitable for 100Mbit ethernet"
causes the following error message when trying to load a file using 'tftp'
command via a tftp server.
TFTP error: 'Unsupported option(s) requested' (8)
This is due to with commit 620776d changes, the tftp option 'timeout'
value is now set to zero which is an invalid value as per RFC2349 [1].
Valid values range between "1" and "255" seconds, inclusive. With some
tftp servers that strictly implement the RFC requirement, it reports
such an error message.
Revert commit 620776d for RFC compliance.

Adjust timouts and retry counts to be suitable for loaded ethernet
network. With 5 seconds timeout, 10 retries maximum, tftp is
impossible even on local network with single full-speed TCP
connection.
100msec timeout should be suitable for most networks tftp is used on,
that is local ethernets. Timeout count really needs to be way higher,
as lost packets are normal when TCP is running over the same network.
Enforce 10msec minimum.

CONFIG_TFTP_TSIZE should limit a tftp downloads progress to 50 '#'
chars. Make this work also for small files.
If the file size is small, i.e. smaller than 2 tftp block sizes the
number of '#' can get much larger. i.e. with a 1 byte file 65000
characters are printed, with a 512 byte file around 500.
When using CONFIG TFTP BLOCKSIZE together with CONFIG_IP_DEFRAG the
issue is more notable.

Previously the net functions would access memory assuming physmem did

NetServerEther was not being cleared in the tftp server code, so the
destination MAC address would be whatever the last destination MAC
address was.
Scenario:
U-Boot:
dhcp
tftpsrv
Host:
Send device WRQ
Device:
Responds with ACK to dhcp server mac address with
host ip address
By clearing NetServerEther, we force a lookup of the host MAC address
to go with the associated host IP.

The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.
In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.

When building u-boot as 64 bit application (e.g. sandbox) ulong might be
64 bits in size. This breaks network code as IPaddr_t is 64 bytes in
size then and an IPv4 address is 32 bits in size. This patch makes sure
that IPaddr_t is always 32 bits in size. Also some warnings introduced
by this patch are fixed.

So far, TFTP negotiated a fixed retransmission timeout of 5 seconds.
In some cases (busy networks, slow TFTP servers) this caused very
slow transfers. A new environment variable "tftptimeout" allows to
set this timeout. Lowering this value may make downloads succeed
faster in networks with high packet loss rates or with unreliable
TFTP servers.

Optionally add RFC 2349 "Transfer Size Option", so we can minimize the
time spent sending data over the UART (now print a single line during a
tftp transfer).
- If turned on (CONFIG_TFTP_TSIZE), U-Boot asks for the size of the file.
- if receives the file size, a single line (50 chars) are printed.
one hash mark == 2% of the file downloaded.
- if it doesn't receive the file size (the server doesn't support RFC
2349, prints standard hash marks (one mark for each UDP frame).
