Date: Sat, 9 Jan 2016 16:07:22 +0100 From: Hannes Frederic Sowa <hannes@...essinduktion.org> To: netdev@...r.kernel.org Cc: jesse@...nel.org Subject: [PATCH net-next v4 00/10] net: break dependency of drivers on geneve and vxlan Device drivers which support geneve or vxlan offloading have a dependency on the correlating tunnel kernel modules. Thus those drivers automatically load the geneve or vxlan modules. Break this dependency with this small series. Additionally this series features a review of the respective ->ndo_open and other functions around vxlan_get_rx_port and geneve_get_rx_port. * Result: $ cd drivers/net/ethernet/ $ find . -name '*.ko' | xargs modinfo | egrep '^depends:.*(vxlan|geneve)' | wc -l 0 I also incorporated feedback from Jesse Gross to only use one new netdevice notifiers type, namely NETDEV_REFRESH_OFFLOADS. Otherwise this series is very much the same as v1. This series (v4) incorperates further feedback from Jesse Gross: * before calling down to the ndo_add_{vxlan,geneve}_port, check if the driver has actually installed the function * provide only one callback function, namely netdev_refresh_offloads * provide updates to the comments in netdevice.h how driver should handle those functions Hannes Frederic Sowa (10): qlcnic: protect qlcnic_82xx_io_slot_reset with rtnl lock mlx4: add rtnl lock protection in mlx4_en_restart ixgbe: add rtnl locking in service task around vxlan_get_rx_port benet: add rtnl lock protection around be_open in be_resume fm10k: add rtnl lock protection in fm10k_io_resume netdev: add netdevice notifier type to trigger a reprogramming of offloads vxlan: break dependency to network drivers geneve: break dependency to network drivers net: harmonize vxlan_get_rx_port and geneve_get_rx_port to netdev_refresh_offloads netdev: update comments and explain idempotency and rtnl locking drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c | 4 +- drivers/net/ethernet/broadcom/bnxt/bnxt.c | 2 +- drivers/net/ethernet/emulex/benet/be_main.c | 11 +++--- drivers/net/ethernet/intel/fm10k/fm10k_netdev.c | 2 +- drivers/net/ethernet/intel/fm10k/fm10k_pci.c | 2 + drivers/net/ethernet/intel/i40e/i40e_main.c | 7 +--- drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 6 ++- drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 4 +- .../net/ethernet/netronome/nfp/nfp_net_common.c | 2 +- drivers/net/ethernet/qlogic/qlcnic/qlcnic_main.c | 12 ++++-- drivers/net/geneve.c | 37 ++++++++++++++---- drivers/net/vxlan.c | 20 +++++++--- include/linux/netdevice.h | 45 ++++++++++++++-------- include/net/geneve.h | 10 +---- include/net/vxlan.h | 8 ---- 15 files changed, 105 insertions(+), 67 deletions(-) -- 2.5.0
