Subject: [PATCH net-next v2 0/6] Allow to switch off UDP-based tunnel offloads per netdevice
Date: Fri, 21 Jul 2017 12:49:27 +0200	[thread overview]
Message-ID: <cover.1500632570.git.sd@queasysnail.net> (raw)

This patchset adds a new netdevice feature to toggle RX offloads of
UDP-based tunnel via ethtool. This is useful if the offload is causing
issues, for example if the hardware is buggy.

The feature is added to all devices providing the ->ndo_udp_tunnel_add
op, and enabled by default to preserve current behavior.

When the administrator disables this feature on a device, all
currently offloaded ports are cleared from the device.  When the
feature is turned on, the stack notifies the device about all current
ports.

v2:
 - rename feature bit to NETIF_F_RX_UDP_TUNNEL_PORT
 - rename ethtool feature to rx-udp_tunnel-port-offload


Sabrina Dubroca (6):
  net: add new netdevice feature for offload of RX port for UDP tunnels
  net: check UDP tunnel RX port offload feature before calling tunnel
    ndo ndo
  net: add infrastructure to un-offload UDP tunnel port
  net: call udp_tunnel_get_rx_info when NETIF_F_RX_UDP_TUNNEL_PORT is
    toggled
  geneve/vxlan: add support for NETDEV_UDP_TUNNEL_DROP_INFO
  geneve/vxlan: offload ports on register/unregister events
