Hi,
We have a patch with fix for an issue raised by Microsoft :
"FreeBSD 11.2 - Kernel panic when flapping network interfaces on and off" .
The issue was observed when the customer was trying to flap interface on and off in a loop more than 20 times. After investigation, it was found that panic occurred due to a thread sleeping while holding a mutex after a calling function pause().
I have attached the patch that has to be submitted upstream. Please let me know if I need to add someone for reviewing it. Also, please let me know if you have any questions.
Thank you,
Anand A. Khoje
