kernel/3.10: improve fq_codel hashing for 6in4 6to4 801.ad and IPIP cases

This is a backport of code to improve the quality of fq_codel
hashing for 3.10 for some encapsulated protocols.

Not needed in 3.11 and later.

ar71xx: Add support for MikroTik RB951Ui-2HnD

I noticed that the patch at http://patchwork.openwrt.org/patch/4017/
for adding support for the MikroTik RouterBOARD 951Ui-2HnD had been
abandoned because it wasn't generated and sent to the mailing list
correctly and doesn't apply as a result.  I have cleaned up this patch.

When testing this on real hardware, I also noticed that wireless didn't
work, so this patch fixes that as well.

This patch applies cleanly to SVN 39392.

[juhosg:
  - drop the 'rb951ui_wlan_init' function and rework the code to
    use the recently introduced rb95x_wlan_init function instead,
  - fix GPIO number of the port5 LED,
  - rename LEDs according to the standard LED naming conventions,
    and use 'rb' prefix in the names]

ar71xx: rb91x: fix pll_1000 value for eth0 to avoid packet loss

When the RB91x device uses a GbE link the connection
suffers from packet loss:

  root@OpenWrt:/# ping 192.168.1.254 -s 65507 -c 20 -q
  PING 192.168.1.254 (192.168.1.254): 65507 data bytes

  --- 192.168.1.254 ping statistics ---
  20 packets transmitted, 9 packets received, 55% packet loss
  round-trip min/avg/max = 4.570/4.815/4.999 ms

Using a different PLL value fixes the issue.

  --- 192.168.1.254 ping statistics ---
  100 packets transmitted, 100 packets received, 0% packet loss
  round-trip min/avg/max = 4.449/5.413/13.870 ms
