57cad53f4e bcm4908: enable & setup packet steering
Without packet steering NAT masquarade speed on BCM4908 /jumps/ between
two speeds:
1. 826 Mb/s (±3 Mb/s)
2. 909 Mb/s (±8 Mb/s)
and it never reaches ~940 Mb/s.

Proper packet steering can improve it. Below are testing results for
running iperf TCP traffic from LAN to WAN. They were used to pick up
golden values.

85b1f4d8ca treewide: remove execute bit and shebang from board.d files
So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.

Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

Note:

This removes an apparantly unused '#!/bin/sh /etc/rc.common' in
target/linux/bcm47xx/base-files/etc/board.d/01_network
