Subject: [PATCH net-next v4 0/7] net: stmmac: FPE via ethtool + tc

Move the Frame Preemption(FPE) over to the new standard API which uses
ethtool-mm/tc-mqprio/tc-taprio.

Changes in v4:
  1. reorder FPE-related declarations and definitions into clean groups
  2. move mm_lock to stmmac_fpe_cfg.lock
  3. protect user configurations across NIC up/down
  4. block stmmac_set_mm() when fpe_task is in progress to finish
  5. convert to ethtool_dev_mm_supported() to check FPE capability in
  tc-mqprio/tc-taprio
  6. silence FPE workqueue start/stop logs

Changes in v3:
  1. avoid races among ISR, workqueue, link update and
  register configuration.
  2. update FPE verification retry logic, so it retries
  and fails as expected.

Changes in v2:
  1. refactor FPE verification processe
  2. suspend/resume and kselftest-ethtool_mm, all test cases passed
  3. handle TC:TXQ remapping for DWMAC CORE4+

Furong Xu (7):
  net: stmmac: move stmmac_fpe_cfg to stmmac_priv data
  net: stmmac: drop stmmac_fpe_handshake
  net: stmmac: refactor FPE verification process
  net: stmmac: configure FPE via ethtool-mm
  net: stmmac: support fp parameter of tc-mqprio
  net: stmmac: support fp parameter of tc-taprio
  net: stmmac: silence FPE kernel logs
