Hi,
In the scenario, tcp server side IP changed, and at that memont,
userspace application still send data continuously;
tcp_send_head(sk)'s timestamp always be refreshed.
Here is the packetdrill script:
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR,

Hi
I find it caused by below steps:
1. set tp_version to TPACKET_V3 and req->tp_block_nr to 1
2. set tp_block_nr to 0
Then pg_vec was freed, and we did not delete the timer?

Hi,
Do we need delete the v3 ring, when tp_version changed from TPACKET_V3 to
TPACKET_V1 ?
