---------------------------
What: CONFIG_NF_CT_ACCT
When: 2.6.29
Why: Accounting can now be enabled/disabled without kernel recompilation.
Currently used only to set a default value for a feature that is also
controlled by a kernel/module/sysfs/sysctl parameter.
Who: Krzysztof Piotr Oledzki <ole@ans.pl>

What: sysfs ui for changing p4-clockmod parameters
When: September 2009

If this option is enabled, the connection tracking code will
keep per-flow packet and byte counters.
Those counters can be used for flow-based accounting or the

Please note that currently this option only sets a default state.
You may change it at boot time with nf_conntrack.acct=0/1 kernel

You may also disable/enable it on a running system with:
