conntrack: api: add nfct_snprintf_labels
nfct_snprintf doesn't print connlabels, as they're system specific
and can easily generate lots of output.
This adds a new helper function, nfct_snprintf_labels. It behaves like
nfct_snprintf, except that the label names in the labelmap whose bits are
contained in connlabel attribute bitset are added to the buffer.
output looks like this:
output looks like this:
... mark=0 use=1 labels=eth0-in,eth1-in
or
<labels>
<label>eth0-in</label>
<label>eth1-in</label>
</labels>
