make test failed. Is sai_switch_notification_t deprecaited or missing?

[ncalad]

When running make test, I encounter a build error because sai_switch_notification_t seems to be missing.

./basic_router.cpp:76:1: error: ‘sai_switch_notification_t’ does not name a type; did you mean ‘sai_switch_stat_t’?
