And if other TID packets received for the peer it will be redirected to rx error ring and not through reo ring. And this rx tid configuration cannot be done in the rx error ring path since it is a atomic context. So moving the rx tid setup for all tids during the peer setup. This is required to enable PN offload functionality to route all packets through reo ring.
