[NETFILTER]: ULOG/nfnetlink_log: Use better default value for 'nlbufsiz'
Performance tests showed that ULOG may fail on heavy loaded systems
because of failed order-N allocations (N >= 1).
The default value of 4096 is not optimal in the sense that it actually
allocates _two_ contigous physical pages. Reasoning: ULOG uses
alloc_skb(), which adds another ~300 bytes for skb_shared_info.
This patch sets the default value to NLMSG_GOODSIZE and adds some
documentation at the top.
