The patch adds ERSPAN type II tunnel support. The implementation is based on the draft at https://tools.ietf.org/html/draft-foschiano-erspan-01. One of the purposes is for Linux box to be able to receive ERSPAN monitoring traffic sent from the Cisco switch, by creating a ERSPAN tunnel device. In addition, the patch also adds ERSPAN TX, so traffic can also be encapsulated into ERSPAN and sent out. The implementation reuses the key as ERSPAN session ID, and field 'erspan' as ERSPAN Index fields: ./ip link add dev ers11 type erspan seq key 100 erspan 123 \ local 172.16.1.200 remote 172.16.1.100 Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: Meenakshi Vohra <mvohra@vmware.com> |
