It receives traffic via igb0 (I210) and pass it with encryp= tion via IPsec tunnel mode via igb1 (I210 too). CPU supports AES-NI, so it is enabled. I'm using aes-128-gcm cipher. Incoming traffic has characteristics which allow to employ all 4 queues of igb0, which run on 4 cores of 4-core CPU, it could be seen in "top -SH" out= put and under heavy load queues consume 400% of CPU, 100% each. Everything work= s as expected. But when I set "sysctl net.inet.ipsec.async_crypto=3D1" strange thing happe= ns: some igb0 queues stop to work. Sometimes it is 1 queue, sometimes 2 queues,= and sometimes 3 (I never seen 4 queues stop to work, though). Stopped queues do= n't consume CPU and don't pass traffic, so 1/4, 2/4 or 3/4 of incoming traffic = is simply lost. Even if traffic is very light (say, 64 packet per second!), traffic which was classified to "stopped" queues is lost. "tcpdump -i igb0" doesn't show it. Only reboot reset this behavior, setting "sysctl net.inet.ipsec.async_crypt= o=3D0" doesn't help. --=20 You are receiving this mail because: You are the assignee for the bug.=
