Given the following bridge rules:
1. ip protocol icmp accept
2. ether type vlan vlan type ip ip protocol icmp accept
The are currently both dumped by "nft list ruleset" as
1. ip protocol icmp accept
2. ip protocol icmp accept
Though, the netlink code actually is different
bridge filter FORWARD 4
[ payload load 2b @ link header + 12 => reg 1 ]
[ cmp eq reg 1 0x00000008 ]
[ payload load 1b @ network header + 9 => reg 1 ]
[ cmp eq reg 1 0x00000001 ]
[ immediate reg 0 accept ]
bridge filter FORWARD 5 4
[ payload load 2b @ link header + 12 => reg 1 ]
[ cmp eq reg 1 0x00000081 ]
[ payload load 2b @ link header + 16 => reg 1 ]
[ cmp eq reg 1 0x00000008 ]
[ payload load 1b @ network header + 9 => reg 1 ]
[ cmp eq reg 1 0x00000001 ]
[ immediate reg 0 accept ]
What happens here is that:
1. vlan type ip kills ether type vlan
2. ip protocol icmp kills vlan type ip
Fix this by avoiding the removal of all vlan statements
in the given example.

This generates the same code as bridge does, but it includes this check
in first place.
[ meta load iiftype => reg 1 ]
[ cmp eq reg 1 0x00000001 ]

Rearrange the directory to obtain a better organization of files and
tests-suites.
We end with a tree like this:
tests
|
.--- py
.--- shell
.--- files
This was suggested by Pablo.
