Enhance opx-config-mirror to accept the list of source interfaces

[atanu-mandal]

opx-config-mirror utility needs to be enhanced to accept the list of source interfaces, currently it accepts only one.

As a workaround, we can follow the below command to configure the list of source interfaces.

# cps_set_oid.py -qua target -oper create base-mirror/entry dst-intf=26 intf,0,src=27 intf,0,direction=1 intf,1,src=32 intf,1,direction=1 type=1

Here dst-intf and src-intf are denoted as “ifindex” instead of interface name.
We can find the ifindex for any interfaces from “ip link show” command (I’ve provided the capture below).

src interfaces : e101-022-0,e101-027-0
dest interface: e101-021-0
type=1 : Span
direction=1 (for ingress)/2(egress)/3(ingress and egress)

• ip link show to find the ifindex :
