Why the MySQL EOF and OK protocol length need add 4? about pisanix HOT 4 CLOSED

https://dev.mysql.com/doc/internals/en/packet-EOF_Packet.html

In this doc, I think 9 length packet include the header.

hi @dongzl
In this example，the 4 bytes is header packet，the data length is 5 bytes. The length of payload is 9 bytes.
You are right, could you please commit a pr to fix this issue?

4 means length of header，I think length of packet means the length of payload， otherwise this don't need to add 4 here.
