Description
Up until this point, all testing against X710/X722 parts has shown two different behaviors with regards to the implicit L2 filter on the Default VSI.
1. The Default VSI has an implicit L2 filter for the factory MAC address and it counts against the total number of L2 filters used.
2. The same as #1 but it DOES NOT count against the total used.
But recently a customer seems to have encountered a third behavior:
3. The Default VSI DOES NOT have an implicit L2 filter for the factory MAC address.
This third behavior causes `i40e_config_def_vsi()` to fail and the following message to be printed to the logs.
2018-12-05T14:59:26.886836+00:00 tcn002 i40e: [ID 517869 kern.warning] WARNING: i40e0: Failed to remove primary MAC from default VSI: -53 (2)
This message is saying that the request to delete the primary (aka factory) MAC has failed with ENOENT. Here is the code:
/*
* The controller places an implicit L2 filter for the primary
* MAC pointing to the default VSI. We remove this filter to
* prevent duplicate delivery of packets destined for the
* primary MAC address as DLS will create the same filter on a
* non-default VSI for the primary MAC client.
*/
bzero(&filt, sizeof (filt));
bcopy(hw->mac.port_addr, filt.mac_addr, ETHERADDRL);
filt.flags = I40E_AQC_MACVLAN_DEL_PERFECT_MATCH;
filt.vlan_tag = 0;
ASSERT3U(i40e->i40e_resources.ifr_nmacfilt_used, <=, 1);
err = i40e_aq_remove_macvlan(hw, I40E_DEF_VSI_SEID(i40e), &filt, 1,
NULL);
if (err != I40E_SUCCESS) {
i40e_error(i40e, "Failed to remove primary MAC from default VSI"
": %d (%d)", err, hw->aq.asq_last_status);
return (B_FALSE);
}
And here is the information for the controller the customer is running:

The current assumption is that this controller/firmware lacks the implicit filter. But it's worth pointing out that the code assumes the implicit filters is a untagged traffic filter. Perhaps there is a chance that the filter is for any tagged traffic (i.e. created with the I40E_AQC_MACVLAN_ADD_IGNORE_VLAN flag).
