How set CONNMARK - NFTA_TARGET_INFO parameter about pyroute2

[BlackSmith]

OK, OK, my mistake.

> from pyroute2.nftables.main import NFTables
> from pyroute2.common import hexload
> from pyroute2.nftables.expressions import genex

> conmark = genex('target', {'name': 'CONNMARK', 'rev': 2,  'info': hexload('00:00:00:00:ff:ff:ff:ff:ff:ff:ff:ff:00:00:02:00')})
> print(conmark)
{'attrs': [('NFTA_EXPR_NAME', 'target'), ('NFTA_EXPR_DATA', {'attrs': [('NFTA_TARGET_NAME', 'CONNMARK'), ('NFTA_TARGET_REV', 2), ('NFTA_TARGET_INFO', b'\x00\x00\x00\x00\xff\xff\xff\xff\xff\xff\xff\xff\x00\x00\x02\x00')]})]}


> nft = NFTables(nfgen_family=2)
> nft.begin()

> nft.rule('add', table='mangle', chain='OUTPUT', expressions=((conmark, ), ) )

The problem was with expressions attribute, it requires tuple in tuple (list in list).

Oh thanks. This part is missing documentation, and it's so complicated that I'm not sure how to start with :)

So thanks for such cases, they definitely will help me with documenting the NFTables API
