[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+
