v3:
- Adressed Pravin's feedback:
- Use #ifdef to check for skb_vlan_tag_present instead of autoconf
- Include <net/vxlan.h> base don USE_KERNEL_TUNNEL_API instead of
separate autoconf check
- Removed now used HAVE_VXLAN_XMIT_SKB_XNET_ARG check
- New patch to account for xnet attribtue in upstream
vxlan_xmit_skb() to keep code more in sync
- New patch to account for new vxflags and removed vxlan_sock
attribute to vxlan_xmit_skb() as changed in net-next in by Tom.
v2:
- Documentation in vswitch.xml and section in ovs-ofctl(8)
- New test in ovs-ofctl.at to check OXM/NXM availability
This series accounts for various upstream kernel changes and then
introduces VXLAN-GBP:
Introduces support for the group policy extension to the VXLAN virtual
port. The extension is disabled by default and only enabled if the user
has provided the respective configuration.
ovs-vsctl add-port br0 vxlan0 -- \
set Interface vxlan0 type=vxlan options:exts=gbp
The configuration interface to enable the extension is based on a new
attribute OVS_VXLAN_EXT_GBP nested inside OVS_TUNNEL_ATTR_EXTENSION
which can carry additional extensions as needed in the future.
The group policy metadata is stored as binary blob (struct ovs_vxlan_opts)
internally just like Geneve options but transported as nested Netlink
attributes to user space.
Renames the existing TUNNEL_OPTIONS_PRESENT to TUNNEL_GENEVE_OPT with the
binary value kept intact, a new flag TUNNEL_VXLAN_OPT is introduced.
The attributes OVS_TUNNEL_KEY_ATTR_VXLAN_OPTS and existing
OVS_TUNNEL_KEY_ATTR_GENEVE_OPTS are implemented mutually exclusive.
