cleanup ethdev close operation

This is the end of a process started two years ago, to have a close which reliably releases an ethdev port without the need of removing the device (which can have more ports). Unfortunately, some drivers might be broken because did not follow the migration recommendations. We cannot wait more, this should be merged before the 20.11-rc1 release. v3: - integrate NXP patches for dpaa, dpaa2, enetc and pfe - fix crash in rte_eth_dev_release_port() because of early memset 0 v2 (big thanks to Ferruh for the reviews): - rebase on top of cxgbe updates - integrate updated patches for tap, bnx2x, qede - return 0 in atlantic PMD - fix failsafe mutex free - remove useless check in pcap - fix testpmd port state transition - add primary process check - reset more pointers in rte_eth_dev_release_port() - remove dev_started reset in rte_eth_dev_close() - return int from rte_eth_dev_close() Note for future: fix old memory leak when releasing port, i.e. free callbacks link_intr_cbs, post_rx_burst_cbs, pre_tx_burst_cbs. The last 3 patches are optional changes to ethdev close/release which were requested by Ferruh but may take longer to be accepted: - memset 0 - keep start state - int return Rasesh Mody (2): net/bnx2x: release port upon close net/qede: release port upon close Sachin Saxena (4): net/dpaa: release port upon close net/dpaa2: release port upon close net/enetc: release port upon close net/pfe: release port upon close Thomas Monjalon (22): ethdev: reset device and interrupt pointers on release ethdev: allow drivers to return error on close net/af_packet: release port upon close net/atlantic: release port upon close net/axgbe: release port upon close net/bonding: release port upon close net/failsafe: release port upon close net/mlx4: release port upon close net/null: release port upon close net/octeontx: release port upon close net/pcap: release port upon close net/ring: release port upon close net/softnic: release port upon close ethdev: remove old close behaviour drivers/net: accept removing device without any port drivers/net: check process type in close operation drivers/net: remove redundant MAC addresses freeing app/testpmd: reset port status on close notification app/testpmd: align behaviour of multi-port detach ethdev: remove forcing stopped state upon close ethdev: reset all when releasing a port ethdev: allow close function to return an error Yunjian Wang (1): net/tap: release port upon close MAINTAINERS | 6 +- app/test-pmd/config.c | 7 +- app/test-pmd/testpmd.c | 53 +++------ app/test/virtual_pmd.c | 6 +- doc/guides/rel_notes/deprecation.rst | 7 -- doc/guides/rel_notes/release_20_11.rst | 4 +- drivers/net/af_packet/rte_eth_af_packet.c | 58 +++++----- drivers/net/af_xdp/rte_eth_af_xdp.c | 9 +- drivers/net/ark/ark_ethdev.c | 17 ++- drivers/net/atlantic/atl_ethdev.c | 62 ++++------- drivers/net/avp/avp_ethdev.c | 10 +- drivers/net/axgbe/axgbe_ethdev.c | 17 +-- drivers/net/bnx2x/bnx2x_ethdev.c | 16 ++- drivers/net/bnxt/bnxt_ethdev.c | 16 ++- drivers/net/bnxt/bnxt_reps.c | 11 +- drivers/net/bnxt/bnxt_reps.h | 2 +- drivers/net/bonding/eth_bond_private.h | 2 +- drivers/net/bonding/rte_eth_bond_pmd.c | 33 +++--- drivers/net/cxgbe/cxgbe_ethdev.c | 18 ++-- drivers/net/cxgbe/cxgbe_main.c | 2 - drivers/net/cxgbe/cxgbe_pfvf.h | 2 +- drivers/net/cxgbe/cxgbevf_ethdev.c | 5 +- drivers/net/cxgbe/cxgbevf_main.c | 2 - drivers/net/dpaa/dpaa_ethdev.c | 124 ++++++++++------------ drivers/net/dpaa2/dpaa2_ethdev.c | 96 +++++++---------- drivers/net/e1000/em_ethdev.c | 18 ++-- drivers/net/e1000/igb_ethdev.c | 36 +++---- drivers/net/ena/ena_ethdev.c | 20 ++-- drivers/net/enetc/enetc_ethdev.c | 17 +-- drivers/net/enic/enic_ethdev.c | 9 +- drivers/net/enic/enic_vf_representor.c | 8 +- drivers/net/failsafe/failsafe.c | 24 +---- drivers/net/failsafe/failsafe_ether.c | 6 +- drivers/net/failsafe/failsafe_ops.c | 67 ++++++++---- drivers/net/failsafe/failsafe_private.h | 1 + drivers/net/fm10k/fm10k_ethdev.c | 22 +--- drivers/net/hinic/hinic_pmd_ethdev.c | 22 ++-- drivers/net/hns3/hns3_ethdev.c | 15 +-- drivers/net/hns3/hns3_ethdev_vf.c | 16 +-- drivers/net/i40e/i40e_ethdev.c | 16 +-- drivers/net/i40e/i40e_ethdev_vf.c | 17 ++- drivers/net/iavf/iavf_ethdev.c | 18 ++-- drivers/net/ice/ice_dcf_ethdev.c | 12 +-- drivers/net/ice/ice_ethdev.c | 21 ++-- drivers/net/igc/igc_ethdev.c | 17 ++- drivers/net/ionic/ionic_ethdev.c | 17 ++- drivers/net/ipn3ke/ipn3ke_ethdev.c | 6 +- drivers/net/ipn3ke/ipn3ke_representor.c | 7 +- drivers/net/ixgbe/ixgbe_ethdev.c | 33 ++---- drivers/net/kni/rte_eth_kni.c | 25 ++--- drivers/net/liquidio/lio_ethdev.c | 11 +- drivers/net/memif/rte_eth_memif.c | 11 +- drivers/net/mlx4/mlx4.c | 7 +- drivers/net/mlx5/linux/mlx5_os.c | 2 - drivers/net/mlx5/mlx5.c | 16 +-- drivers/net/mlx5/mlx5.h | 2 +- drivers/net/mvneta/mvneta_ethdev.c | 15 +-- drivers/net/mvpp2/mrvl_ethdev.c | 15 +-- drivers/net/netvsc/hn_ethdev.c | 19 ++-- drivers/net/netvsc/hn_var.h | 2 +- drivers/net/netvsc/hn_vf.c | 7 +- drivers/net/nfb/nfb_ethdev.c | 11 +- drivers/net/nfp/nfp_net.c | 11 +- drivers/net/null/rte_eth_null.c | 26 +++-- drivers/net/octeontx/octeontx_ethdev.c | 17 ++- drivers/net/octeontx2/otx2_ethdev.c | 8 +- drivers/net/pcap/rte_eth_pcap.c | 31 +++--- drivers/net/pfe/pfe_ethdev.c | 51 ++++----- drivers/net/qede/qede_ethdev.c | 20 ++-- drivers/net/ring/rte_eth_ring.c | 53 +++++---- drivers/net/sfc/sfc_ethdev.c | 35 +++--- drivers/net/softnic/rte_eth_softnic.c | 67 ++++++------ drivers/net/szedata2/rte_eth_szedata2.c | 23 ++-- drivers/net/tap/rte_eth_tap.c | 52 +++++---- drivers/net/thunderx/nicvf_ethdev.c | 11 +- drivers/net/vhost/rte_eth_vhost.c | 15 +-- drivers/net/virtio/virtio_ethdev.c | 17 ++- drivers/net/virtio/virtio_user_ethdev.c | 4 +- drivers/net/vmxnet3/vmxnet3_ethdev.c | 16 ++- lib/librte_ethdev/rte_ethdev.c | 32 ++---- lib/librte_ethdev/rte_ethdev.h | 13 +-- lib/librte_ethdev/rte_ethdev_driver.h | 2 +- lib/librte_ethdev/rte_ethdev_pci.h | 14 +-- 83 files changed, 763 insertions(+), 928 deletions(-)
