Hi,
I use xdp-loader to load XDP program [0] that tails call XDP
synproxy program that was modified from kernel source [1] on Loongarch
platform, I got message "JIT doesn't support bpf-to-bpf call near the
bottom of the output below:

How to reproduce:
git clone https://github.com/vincentmli/xdp-tools.git
cd xdp-tools; make
./xdp-loader/xdp-loader load -vvv lo -m skb -P 80 -p
/sys/fs/bpf/xdp-synproxy-tailcall -n synproxy_tailcall
./xdp-synproxy-tailcall/xdp_synproxy_tailcall.bpf.o
I have another XDP program [2] also tail calls other XDP program, it
works fine https://github.com/vincentmli/xdp-tools/tree/master/xdp-tailcall
[root@fedora xdp-tools]# ./xdp-loader/xdp-loader load -v lo -m skb -P
80 -p /sys/fs/bpf/xdp-tailcall -n xdp_tailcall
./xdp-tailcall/xdp_tailcall.bpf.o
Current rlimit 8388608 already >= minimum 1048576
