Counters in the ‎abf_input_inline function

[sanosco]

Hi,

There is a question concerning counters in the ‎abf_input_inline function.

Ternary operator looks odd.
https://github.com/FDio/vpp/blob/9370dde53acb0324a6b91cd3d6928273a83ef228/src/plugins/abf/abf_itf_attach.c#L607C1-L616C37

Is it intended to do the following assignments?
fproto = FIB_PROTOCOL_IP6
It looks like abf_ip4_node.index will be always selected.

It is more ordinary for me to encounter something like following.
(fproto == FIB_PROTOCOL_IP6 ? abf_ip6_node.index : abf_ip4_node.index)
