Having the txtest, rxtest and lacp_strict a global sysctls makes them useless on a box that has more than one aggregate interface. Turning test on will down all laggs on a box. IMO, these should be ioctls that can be configured per-interface via ifconfig, and in perfect case documented in ifconfig.8. -- Totus tuus, Glebius.
