Cassandra version 5: unsupported protocol error #1750
Description
What version of Cassandra are you using?
5
What version of Gocql are you using?
v1.6.0
What version of Go are you using?
go1.21.6 linux/amd64
What did you do?
Trying to establish a session with the Cassandra v5 cluster (inside the Docker container) using native protocol v5. I saw that the version 5 protocol was added already, but it seems it is not working properly for some reason. I've debugged the connection process and found that the error happened during the readHeader() function execution.
So, the process of connection according to logs looks like this:

version 114
_error here_
I've compared the connection process using 5 version with 3 and 4 versions of the protocol. It seems pretty similar, except the one thing. When we use the 5 version the first byte always changes from 133 to 114. Now, I am reading the native protocol 5 specification to understand what changes should be made to fix the issue. Will be glad to receive any suggestions regarding it.
Code snippet:
cluster := gocql.NewCluster("172.17.0.2")
cluster.Consistency = gocql.Quorum
cluster.ProtoVersion = 5
cluster.ConnectTimeout = time.Second * 10
session, err := cluster.CreateSession()
if err != nil {
log.Println(err)
return
}
defer session.Close()
