maybe this improves the ENOBUFS situation? it should result in equal or
more messages though as the callback is run multiple times before
nfct_catch returns.
I wouldn't expect a change in the ENOBUFS situation but rather just more
output happening which may have previously been lost from already-read
packet parts.
@Alexandre, could you give this a try?
For ENOBUFS we could try setting NETLINK_NO_ENOBUFS with setsockopt as
mentioned by @Thomas.
