[RFC mptcp-next 00/11] BPF packet scheduler updates part 4

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

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.

Geliang Tang (11):
  Squash to "mptcp: add struct mptcp_sched_ops"
  Squash to "mptcp: add scheduler wrappers"
  mptcp: use snd_burst wrappers
  Squash to "mptcp: register default scheduler"
  Squash to "bpf: Add bpf_mptcp_sched_ops"
  Squash to "selftests/bpf: Add mptcp sched structs"
  Squash to "selftests/bpf: Add bpf_bkup scheduler"
  Squash to "selftests/bpf: Add bpf_rr scheduler"
  Squash to "selftests/bpf: Add bpf_burst scheduler"
  selftests/bpf: Add bpf_stale scheduler
  selftests/bpf: Add bpf_stale test
