[U-Boot] [PATCH 0/4] Network defrag

[Alessandro Rubini <rubini-list@gnudd.com>]

I finally fixed the defrag code, testing with NFS as well.
Didn't take performance figures, tough, for lack of time.

I wanted to do "config + environment" for the NFS case, like tftp, but
didnt' do the second step out of laziness (also, the source file has
long lines while I have 80 columns).

For the record, I added the check on ip_src and ip_dst, but everything
stopped working. So I reverted that instead of entering a long
debugging session.

The CONFIG_NET_MAXDEFRAG argument is the actual payload, so I add NFS
overhead to that figure, which is expected to a beautiful 4096 or
8192.  I feel this is better than other options, as the person writing
the config is not expected to know how much protocol overhead is
there.

Alessandro Rubini (4):
  net: defragment IP packets
  tftp: get the tftp block size from config file and from the
    environment
  nfs: accept CONFIG_NFS_READ_SIZE from config file
  arm nomadik: activate defrag choose 4k transfer block size
