net/ixgbe: fix resource leak after thread exits normally
Checks
Commit Message
From: "Zhu, Tao" <taox.zhu@intel.com>
When the thread exits normally, pthread_join() is not called, which can
result in a resource leak. Therefore, the thread is set to separation
mode using function pthread_detach(), so that no program call
pthread_join() is required to recycle, and when the thread exits,
the system automatically reclaims resources.
