[SLOF] [PATCH 0/7] Netboot / DHCP improvements

[Thomas Huth]

This patch series enhances the netboot and DHCP code in net-snk.
The first patch improves the printed text a little bit.
The next patches introduce transaction ID handling in the DHCPv4
and DHCPv6 code. For this, I had to fix the rand() function in
SLOF's libc first and implement srand() to be able to seed it.
And the last patch fixes a problem with sent DHCPv6 packets - they
contained trailing garbage bytes.

Thomas Huth (7):
  net-snk: Improve printed text when booting via network
  libc: Fix the rand() function to return non-zero values
  libc: Add srand() call
  net-snk: Seed the pseudo-random number generator
  net-snk: Make use of DHCPv6 transaction IDs
  net-snk: Use transaction IDs in DHCPv4, too
  net-snk: Get rid of junk at the end of sent DHCPv6 packets
