Bug#545449: ulog is OBSOLETED in kernel

[MAtteo HCE Valsasna <matteo.valsasna@uninsubria.it>]

looking into kernel documentation, I discovered that ebt_ulog (and also
its counterpart ipt_ulog (which loads fine) are both obsoleted by
NETFILTER_NETLINK_LOG (see below).

BUT, I could not find an alternative netflow probe based on netlink
sockets.


CONFIG_BRIDGE_EBT_ULOG:                                                                                                                              
This option enables the old bridge-specific "ebt_ulog" implementation
which has been obsoleted by the new "nfnetlink_log" code (see
CONFIG_NETFILTER_NETLINK_LOG).   

CONFIG_IP_NF_TARGET_ULOG:                                                                                                                           
This option enables the old IPv4-only "ipt_ULOG" implementationwhich has
been obsoleted by the new "nfnetlink_log" code (see
CONFIG_NETFILTER_NETLINK_LOG).    

 CONFIG_NETFILTER_NETLINK_LOG:
If this option is enabled, the kernel will include support for logging
packets via NFNETLINK.

This obsoletes the existing ipt_ULOG and ebg_ulog mechanisms, and is
also scheduled to replace the old syslog-based ipt_LOG and ip6t_LOG
modules.
