I recall that there was a patch proposed to prevent ageing of fdb entried by bridge in kernel, when the fdb entry was added due to notification by switch device. Please see: http://www.spinics.net/lists/netdev/msg314770.html Somehow the patch is not visible in the net-next pull. -Prem > > As another option for a *per-port* boolean flag for enabling/disabling ageing, > one can think of adding an IFLA_BRPORT_AGEING bool flag (and BR_AGEING) > for IFLA_PROTINFO. > > Regards, > Rami Rosen > Intel Corporation -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
