Hello, all
I am trying using pfbridge in non blocking mode with using
pfring_send_last_rx_packet (see patch below) in next setup:
tap1 <---> pfbridge <---> tap2
and I am getting packets on tap2 delayed by two packets,
i.e.
send packet1 to tap1 --- got nothing on tap2
send packet2 to tap1 --- got nothing on tap2
send packet3 to tap1 --- got packet1 on tap2
send packet4 to tap1 --- got packet2 on tap2
.....
when I using blocking mode (original code withot patch) it works fine,
as well as using -p option (without pfring_send_last_rx_packet)
Tested on tap devices and tg3 original linux driver.
