TCP_PSP_RX_SPI_KEY failed: Operation not supported #66

Description

@lya1016

I was about to use psp_rr.c to start psp connection between two terminals.

server$ ./psp_rr -H fe80::20c:29ff:fe5d:4a9d%ens33
client$ ./psp_rr -c -H fe80::20c:29ff:fe5d:4a9d%ens33 -L fe80::20c:29ff:fe5d:4a9d%ens33

I started then the client terminal said "TCP_PSP_RX_SPI_KEY failed: Operation not supported".
The sever terminal said "Unexpected EOF on key management connection
ctrl_wait_client: Read error: read want 72 bytes, magic 42 type 3, have 0 0 0"

I used the kernel from github: google/psp: "https://github.com/google/psp/tree/linux-v5.15-psp-v1.0?tab=readme-ov-file" and I set psp config: "[*] IP: PSP Security Protocol". Do I config wrong or something else?
