Re: [tipc-discussion] TIPC_WITHDRAW event comes late

[Ying X. <yin...@wi...>]

Please validate whether it appears with the latest kernel.

If you cannot, please provide more detailed info:

1. Capture TIPC packets with tcpdump tool;
2. Provide dmesg log, but be sure each line of demeg logs should be
prefixed by timestamps.
3. Print timestamp as well when you receive TIPC_WITHDRAW on user land.
