af_packet: remove UNIX_FILE_EVENT_EDGE_TRIGGERED flag
af_packet does not process data until the interface is UP. If after interface creation, but before it is UP, the host interfaces are flooded, then blocking case may occur - VPP interface will never be able to process the data.
If the EDGE_TRIGGERED flag is set, the event will not arrive, because nothing new is happening anymore (probably because the queue is already full).
Therefore, we need to use LEVEL_TRIGGERED (default value), which indicates that there is still unprocessed data (accumulated after interface creation, but before it was UP).
Type: fix
