Symptoms

At bootup, there is a possibility of tmm crashing while coming up when the configuration contains an AFM address-list whitelist on an sPVA hardware platform.

Impact

tmm will crash and restart. Traffic disrupted while tmm restarts.

Conditions

Configuration contains AFM address-list whitelist on an sPVA HW platform, and the race condition happens in which tmm and mcpd start interacting before the hardware HSB is ready.

Workaround

Remove the AFM address-list whitelist, and then configure it once the system is up.

Fix Information

TMM no longer crashes at bootup if an AFM DoS address-list whitelist is present in sPVA hardware platforms.
