```
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
1. start proxy
2. config proxy `CREATE ENCRYPT RULE sbtest1 (
COLUMNS(
(NAME=c,CIPHER=c,TYPE(NAME=AES,PROPERTIES('aes-key-value'='123456abc')))
));`
3. start MySQL
4. use sysbench prepare data to MySQL,without proxy
5. use proxy execute `select `

MySQL maintain a field `pkt_nr` in `NET` to hold sequence ID for current connection.

Sequence ID would be verified when reading packet headers.

To fix this issue, we have to refactor MySQLPacket. Removing the sequence ID from MySQLPacket and handling sequence ID in Codec.

If we set the sequence ID (AKA Packet Number in Wireshark) correctly, the MySQL cli will not exit.
