> Make TPACKET_V3 signal poll when block is closed rather than for every > packet. Side effect is that poll will be signaled when block retire timer > expires which didn't previously happen. Issue was visible when sending > packets at a very low frequency such that all blocks are retired before > packets are received by TPACKET_V3. This caused avoidable packet loss. The > fix ensures that the signal is sent when blocks are closed which covers the > normal path where the block is filled as well as the path where the timer > expires. The case where a block is filled without moving to the next block > (ie. all blocks are full) will still cause poll to be signaled.
