2018-01-16tapv2: deleting tap interface may leak buffers (VPP-1124)Steven1-2/+2
Buffers may be allocated for indirect descriptors by tx thread and they are freed when tx thread is invoked in the next invocation. This is to allow the recipient (kernel) to have a chance to process them. But if the tap interface is deleted, the tx thread may not yet be called to clean up the indirect descriptors' buffers. In that case, we need to remove them without waiting for the tx thread to be called. Failure to do so may cause buffers leak when the tap interface is deleted. For the RX ring, leakage also exists for vring->buffers when the interface is removed.
