Alexander Drozdov 41a50d621a af_packet: don't pass empty blocks for PACKET_V3 ... Before da413eec72 ("packet: Fixed TPACKET V3 to signal poll when block is closed rather than every packet") poll listening for an af_packet socket was not signaled if there was no packets to process. After the patch poll is signaled evety time when block retire timer expires. That happens because af_packet closes the current block on timeout even if the block is empty. Passing empty blocks to the user not only wastes CPU but also wastes ring buffer space increasing probability of packets dropping on small timeouts.
