This is another round of stmmac selftest fixes, mostly about the selftests themselves but a few things were discovered w.r.t MTU and buffer size handling, see patch 5. I've continued expanding the test devices I'm running this on, more devices should come in the future. With this series, _almost_ everything is green, except for some flow control stuff that is either a false positive or a real thing that needs investigating. After this is merged, I consider the selftests to be now reliable enough to run them nightly on every stmmac series that's sent, and I'll be requiring clean selftests for new glue drivers. I've been running this on : - Altera CycloneV (dwmac-socfpga, dwmac1000 IP, v3.70a) - NXP imx8mp (dwmac-imx, dwmac4, v5.10a) - Allwinner H2S (dwmac-sun8i, dwmac1000) - Amlogic S905X3 (dwmac-meson8b, dwmac1000, v3.70a) - STM32mp157a (dwmac-stm32, dwmac4, v4.20a) - SiFive JH7110 (dwmac-starfive, dwmac4, v5.20) - Motorcomm YT8061 (PCIe, dwmac-motorcomm, dwmac4) - Qualcomm IPQ8064 (dwmac-ipq806x, dwmac1000) Tests are OK if return is 0 or -95 (-EOPNOTSUPP), tests are KO otherwise Before the series : Test imx socfpga sun8i meson8b stm32 starV mcom ipq806x MAC Loopback 0 0 0 0 0 0 0 -110 MMC Counters 0 0 -95 0 0 0 0 -110 EEE -95 -95 -95 -110 -110 -95 -95 -95 Hash Filter MC 0 0 -95 0 0 0 0 -95 Perfect Filter UC -95 0 0 -95 -95 -95 -95 -95 MC Filter -95 0 -95 -95 -95 -95 -95 -95 UC Filter -95 0 -95 -95 -95 -95 -95 -95 Flow Control -95 0 -110 0 -110 -95 -110 -110 RSS -95 -95 -95 -95 -95 -95 -95 -95 VLAN Filtering -110 -95 -95 -95 -110 -110 -95 -95 VLAN Filtering (perf) -110 -95 -95 -95 -110 -110 -95 -95 Double VLAN Filter -110 -95 -95 -95 -110 -110 -95 -95 Double VLAN Filter (perf) -110 -95 -95 -95 -110 -110 -95 -95 Flexible RX Parser 0 -95 -95 -95 -95 -95 -95 -95 SA Insertion (desc) 0 -95 -95 -95 0 0 0 -95 SA Replacement (desc) 0 -95 -95 -95 0 0 0 -95 SA Insertion (reg 0 -95 -95 -95 0 0 0 -95 SA Replacement (reg) 0 -95 -95 -95 0 0 0 -95 VLAN TX Insertion -110 -95 -95 -95 -110 -110 -110 -95 SVLAN TX Insertion -110 -95 -95 -95 -110 -95 -110 -95 L3 DA Filtering 0 -95 -95 -95 -95 -95 -95 -95 L3 SA Filtering 0 -95 -95 -95 -95 -95 -95 -95 L4 DA TCP Filtering 0 -95 -95 -95 -95 -95 -95 -95 L4 SA TCP Filtering 0 -95 -95 -95 -95 -95 -95 -95 L4 DA UDP Filtering 0 -95 -95 -95 -95 -95 -95 -95 L4 SA UDP Filtering 0 -95 -95 -95 -95 -95 -95 -95 ARP Offload -95 -95 -95 -95 -110 -110 -110 -95 Jumbo Frame 0 -110 -110 0 0 0 0 -110 Multichannel Jumbo 0 -95 -95 -95 -95 -95 -95 -95 Split Header --95 -95 -95 -95 -95 -95 0 -95 TBS (ETF Scheduler) --95 -95 -95 -95 -95 -95 -95 -95 ARP offload's still there as this was a net-next patch and I've ran these checks on the net tree. Jumbo frame tests on dwmac1000 started failing after : commit 23680bf5f8c6 ("net: stmmac: restore NET_IP_ALIGN in the RX DMA offset") This commit is OK though, it just made the selftest reveal the cracks hiding beneath the surface of MTU/bufsz handling.
