The number of subflows, when using the in-kernel PM, is currently limited to (like the entrypoints/received add_addr).
Limiting endpoints to 8 makes sense (arrays are used) but not subflows: it looks like there is no technical limits (except with MPTCP_SUBFLOWS_MAX in packet sched in BPF...)
We could go up to UINT8 but probably better to limit to 64 (8x8) as it can be costly to iterate over all subflows when operations are done in bottom half.
We would need a test with 64 subflows for that.
