This is needed for the upcoming TFTP server implementation.

This also simplifies PingHandler() and fixes rxhand_f documentation.

- NfsTimeout() does not correctly update the NFS timeout value which
  results in NfsTimeout() only being called once in certain situations.
  This can result in the 'nfs' command hanging indefinetly.  For
  example, the command:

    nfs 192.168.0.1:/home/user/file

  will not exit until ctrl-c is pressed if 192.168.0.1 does not have an
  NFS server running.

  This issue is resolved by reinitializting the NFS timeout value inside
  NfsTimeout() when a timeout occurs.

- Make the 'nfs' command print the 'T' character when a timeout occurs.
  Previously there was no indication that timeouts were occuring.

- Mimic the 'tftpboot' command and when a download fails print "Retry
  count exceeded; starting again", and restart the download taking the
  'netretry' environment variable into account.

 Minor ./net cleanups - no functional changes
  - change #ifdef DEBUG printf(); #endif to just debug()
  - changed __FUNCTION__ to __func__
  - got rid of extra whitespace between function and opening brace
  - removed unnecessary braces on if statements

 gcc dead code elimination should make this functionally/size equivalent
 when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3).

Now that our printf functions support the %pI4 modifier like the kernel,
let's drop the inflexible print_IPaddr() function and covert over to the
%pI4 modifier.

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

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

Patch by Hiroshi Ito, 06 Dec 2004

  Fix NFS timeout issue

* Increase NFS download timeout (now 1 min - 10 sec is to short for a
  slow download of a big image)

add networking support for VLANs (802.1q), and CDP (Cisco Discovery Protocol)

  - show PCI clock frequency on MPC8260 systems
  - add FCC_PSMR_RMII flag for HiP7 processors
  - in do_jffs2_fsload(), take load address from load_addr if not set
    explicit, update load_addr otherwise
  - replaced printf by putc/puts when no formatting is needed
    (smaller code size, faster execution)

  Fix problems with GCC 3.3.x which changed handling of global
  variables explicitly initialized to zero (now in .bss instead of
  .data as before).

* Patch by Leon Kukovec, 02 Mar 2004:
  add strswab() to fix IDE LBA capacity, firmware and model numbers
  on little endian machines

* Patch by Masami Komiya, 02 Mar 2004:
  - Remove get_ticks() from NFS code
  - Add verification of RPC transaction ID

* Patch by Pierre Aubert, 02 Mar 2004:
  cleanup for IDE and USB drivers for MPC5200

  - Timeouts in FPGA code should be based on CFG_HZ
  - Minor cleanup in code for Altera FPGA ACEX1K

* Patch by Steven Scholz, 25 Feb 2004:
  Changed "Directory Hierarchy" section in README

* Patch by Masami Komiya, 25 Feb 2004:

  Update NetBootFileXferSize in NFS code

* Patch by Scott McNutt, 24 Feb 2004:
