Message

v4:
- rebased on "BPF redundant scheduler, part 2" v24.

v3:
- invoking __mptcp_retrans in __mptcp_subflow_push_pending fails
  with a soft lockup error, so use MPTCP_WORK_RTX instead.
- invoke __mptcp_retrans in __mptcp_push_pending iteratively for each
  dfrag.
- depends on "BPF redundant scheduler, part 2" v23.

v2:
- drop retrans_redundant flag.
- call __mptcp_retrans() directly.
- depends on "BPF redundant scheduler, part 2" v23.

v1:
- The DSS issue has been fixed in this version, and all tests
(mptcp_connect.sh, mptcp_join.sh, simult_flows.sh and BPF test_progs)
passed.
- No need to set already_sent to 0, drop this.
- Add retrans_redundant flag.
- depends on "BPF redundant scheduler, part 2" v22.

Geliang Tang (2):
  mptcp: update mptcp_push_release
  mptcp: retrans for redundant sends
