Bug ID: 245894
Summary: ixl(4) does not support more than 255 VLANs
Product: Base System
Version: 12.1-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: ncrog...@gmail.com
When configuring 256 or more VLAN interfaces on an ixl(4) interface, the
adapter drops frames for the 256th and later configured VIDs. Enabling
promiscuous mode fixes the problem.
Example dmesg output when this happens:
ixl1: i40e_aq_add_macvlan status I40E_ERR_ADMIN_QUEUE_ERROR, error
I40E_AQ_RC_ENOSPC
pciconf -lcv ixl0

This appears to be a firmware problem, but I am not quite sure. The Linux
driver seems to automatically disable promisc mode when the firmware returns
I40E_AQ_RC_ENOSPC after adding a MAC/VLAN filter.
I tried toggling vlanhwfilter and/or vlanhwtag to no avail.
Enabling promisc mode fixes the problem.
It would be nice if the driver did this automatically, or I would like to at
least understand why the firmware does not support this. Is there a way to
disable the MAC/VLAN filtering in the adapter and just rely on the OS?
Thanks for any assistance.
