[RFC mptcp-next v2 0/2] BPF packet scheduler updates part 4
Posted by Geliang Tang 7 months, 4 weeks ago
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.

Geliang Tang (2):
  mptcp: add set/get params wrappers
  mptcp: add bpf_burst set/get params
