Changes in v9: 1. drop redundant netif_device_present() since ethnl_ops_begin() has its own netif_device_present() call 2. open-code some variables of struct ethtool_mm_state directly in struct stmmac_fpe_cfg 3. convert timer_delete_sync() to timer_shutdown_sync(), thus the timer will not be rearmed again 4. fixed variable declarations in the middle of the scope Changes in v8: 1. use timer_delete_sync() instead of deprecated del_timer_sync() 2. check netif_running() to guarantee synchronization rules between mod_timer() and timer_delete_sync() 3. split up stmmac_tc_ops of dwmac4, dwmac4+ and dwxgmac to give user more descriptive error message 4. fix wrong indentation about switch-case 5. delete more unbalanced logs Changes in v7: 1. code style fixes and clean up warnings reported by patchwork netdev checks, no functional change intended Changes in v6: 1. new FPE verification process based on Vladimir Oltean's proposal 2. embed ethtool_mm_state into stmmac_fpe_cfg 3. convert some bit ops to u32_replace_bits 4. register name and function name update to be more descriptive 5. split up stmmac_tc_ops of dwmac4+ and dwxgmac, they have different implementations about mqprio 6. some code style fixes Changes in v5: 1. fix typo in commit message 2. drop FPE capability check in 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 process 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 .../net/ethernet/stmicro/stmmac/dwmac4_core.c | 10 +- drivers/net/ethernet/stmicro/stmmac/dwmac5.c | 96 ++++++- drivers/net/ethernet/stmicro/stmmac/dwmac5.h | 12 +- .../ethernet/stmicro/stmmac/dwxgmac2_core.c | 9 +- drivers/net/ethernet/stmicro/stmmac/hwif.c | 6 +- drivers/net/ethernet/stmicro/stmmac/hwif.h | 22 +- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 35 ++- .../ethernet/stmicro/stmmac/stmmac_ethtool.c | 96 +++++++ .../net/ethernet/stmicro/stmmac/stmmac_main.c | 269 ++++++++---------- .../net/ethernet/stmicro/stmmac/stmmac_tc.c | 153 +++++++--- include/linux/stmmac.h | 28 -- 11 files changed, 494 insertions(+), 242 deletions(-)
