[PATCH 0/2] conntrack: permit updating only a part of the ctmark

[Florian Westphal <fw@strlen.de>]

Hello Pablo,

here are two patches for conntrack(8).

I want to alter the upper 8 bits of the conntrack mark while keeping
the rest intact.  At the moment it is only possible to specifiy
an absolute value, so i've extended --mark to optionally handle
a mask argument.  Its possible to either filter by mark (e.g.
list conntracks with a particular mark bit set) or to update
parts of the mark.

The 2nd patch is not absolutely needed, but it speeds up operation
when only a couple of conntracks are affected by the modification.

Thanks,
Florian
