(tcpmib_local_port): Ditto.
(tcpmib_remote_port): Ditto.
(tcpmib.OutRsts.A): Used '@defined' instead of a kernel version check.

events. The probes mirror many of the SNMP statistics defined
in /usr/include/linux/snmp.h. Each probe represents a single SNMP
statistic or MIB. Each of the probe's handler is called when system
performs an operation that would alter the associated statistic. Along
with each probe is defined an indexed set of counters used to record
probe hits. The probe handlers call a user supplied callback functions
to determine which counter to alter. The user's callback should returns a
key value that will be used to index the counter. For example a callback
could return a unique value for each socket. This would results in a
separate counter being used for each socket.
tcpipstat.stp shows how snmp tapsets could be used. Tcpipstat collects and
displays network statistics related to individual TCP sockets or groups of
sockets. The statistics that are collected are simmer to that of the command
netstat -s, only sorted and grouped by individual sockets.
