Ingest XDP v0.16.7 and use TCP CIBIR rules when needed.
Changes to our tests:
1. 0-RTT tests are disabled. QTIP caches only one packet before handshake completes. So, if multiple 0-RTT packets are sent, only one of them will make it.
2. NAT rebind doesn't apply to TCP. So, they are disabled.
3. Due to implementation limitations, sharing bindings isn't supported. Some tests are tweaked to always create a new binding per connection. For simplicity, the implementation assumes client side sockets have a 1:1 mapping to QUIC connection.
## Description
QTIP (QUIC over TCP): A variant of QUIC with TCP headers instead of UDP headers. This is different from a TCP tunnel in that it does not use TCP’s retransmission and congestion control logic: it simply uses TCP headers (and a few pure TCP SYN and RST packets with no QUIC payload) to masquerade as TCP traffic.
Client Side:
1. When the initial packet is passed down to raw datapath, we cache the send and send a SYN instead.
2. When SYN+ACK is received, we send an ACK and then resume the initial packet and construct a RST to be sent later (because at this moment we know what sequence and ACK numbers to use).
3. When the first data packet is received, we will know what sequence number and ACK number to use. The ACK number after handshake is always acking the peer's SYN+ACK. The sequence number is always ISN+2, where ISN+1 is reserved for RST. By doing so, all data packets are retransmissions but still in window.
4. When the QUIC connection is shut down, the cached RST is sent.
Server side:
1. Statelessly respond to all SYN/FIN received.
2. When the first data packet is received, it's identical to 3.
