VxLAN-GPE NSH decapsulation and encapsulation implementation at data plane
level in kernel space and rules related with NSH match and actions at control
plane level.
The VXLAN-GPE NSH type are enabled in this patch. The design is based on basic
VxLAN implementation. The UDP port 4790 is used for VXLAN-GPE NSH type. When
VxLAN-GPE NSH packets are received from VxLAN-GPE NSH port, the decapsulation
will be implemented and the fields related with NSH will be parsed. When
packets are sent to VxLAN-GPE NSH port, the encapsulation will be implemented
according to the VxLAN-GPE NSH configuration and related rules.
Notes:
(1) port 4790 is for VxLAN-GPE NSH extension.
(2) new options for VxLAN-GPE NSH: service path header(nsp, nsi) and context
header with NSH MD-type 1(nshc1, nshc2, nshc3, nshc4). These fields have
fixed/flow setting: fixed value indicates input value in related field must be
fixed value detected by this port and output value in related field will be set
as fixed value when encapsulation is implemented; flow value indicates the
input value is checked by the openflow rule and output value is set by the
openflow rule.
(3) new related actions: Add 6 new actions for NSH set fields: set_nsp,
set_nsi,set_nshc1,set_nshc1,set_nshc3,set_nshc4
