[PATCH 0/5] IPv6 support

[Viacheslav Mitrofanov]

This patch set adds basic IPv6 support to U-boot. 
It is based on Chris's Packham patches
(https://lists.denx.de/pipermail/u-boot/2017-January/279366.html)
Chris's patches were taken as base. There were efforts to launch it on HiFive
SiFive Unmatched board but the board didn't work well. The code was refactored,
fixed some bugs as CRC for little-endian, some parts were implemented in our own
way, something was taken from Linux. Finally we did manual tests and the board
worked well.

Testing was done on HiFive SiFive Unmatched board (RISC-V)
