>Description:
	On kernels without ipsec (e. g. GENERIC) netstat -s stops output when ipsec stats 
	cannnot be read. This suppresses other statistics such as IPv6 status.

icmp:
	287 calls to icmp_error
	3 errors not generated because old message was icmp
	Output histogram:
[... snip ...]
ip:
	10058246 total packets received
	0 bad header checksums
	0 with size smaller than minimum
	0 with data size < data length
	0 with length > max ip packet size
	0 with header length < data size
	0 with data length < header length
	0 with bad options
	0 with incorrect version number
	332 fragments received
	0 fragments dropped (dup or out of space)
	0 fragments dropped (out of ipqent)
	0 malformed fragments dropped
	0 fragments dropped after timeout
	163 packets reassembled ok
	4494978 packets for this host
	0 packets for unknown/unsupported protocol
	5560577 packets forwarded (0 packets fast forwarded)
	941 packets not forwardable
	0 redirects sent
	0 packets no matching gif found
	4834215 packets sent from this host
	245 packets sent with fabricated ip header
	0 output packets dropped due to no bufs, etc.
	0 output packets discarded due to no route
	78 output datagrams fragmented
	82 fragments created
	0 datagrams that can't be fragmented
	0 datagrams with bad address in header
netstat: net.inet.ipsec.ipsecstats: No such file or directory
[... other statistics missing ...]

>How-To-Repeat:
	Try netstat -s on a GENERIC kernel.

>Fix:
	netstat
