[PATCH mptcp-next v3 0/9] BPF packet scheduler updates part 4

[Geliang Tang <geliang.tang@suse.com>]

v3:
 - store burst in msk->snd_burst instead of in sk_storage.
 - make mptcp_sched_data_set_contexts static.
 - rename mptcp_subflow_ctx_by_pos to bpf_mptcp_subflow_ctx_by_pos, and
   add "__bpf_kfunc" before it.

v2:
 - keep sched API unchanged.
 - use bpf_sk_storage_lookup to get snd_burst from BPF context.
 - applied after "add bpf_stale scheduler v3" serise.

v1:

There's a bug in bpf_burst. snd_burst stored in mptcp_burst_storage in
BPF context is not used. msk->snd_burst is still used in kernel space.
To fix this, add two new interfaces in mptcp_sched_ops to get and set
scheduler's paramters from BPF context to kernel space.
