Hi all! I was chasing a potential segfault and it appears, if I'm reading this driver correctly, that in i40evf_init_vf() the value vf->adapter->eth_dev is never set like pf->adapter->eth_dev is in eth_i40e_dev_init().
I believe this is leading to a segfault when something like i40e_recv_scattered_pkts calls: dev = I40E_VSI_TO_ETH_DEV(rxq->vsi); // dev ends up NULL here dev->data->rx_mbuf_alloc_failed++; // this generates a NULL pointer dereference/segfault I'm not completely confident in my understanding of the PF/VF drivers so I may be missing something; but we are seeing the segfault on those lines in v20.05 at least. I couldn't find a related patch/commit but wanted to check if my reasoning was correct before adding this 1 line fix. Thanks, Stefan Baranoff
