- bnx2x: allow adding VLANs while interface is down
BugLink: http://bugs.launchpad.net/bugs/1616107
Since implementing VLAN filtering in commit
05cc5a39ddb74
("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while
the interface is down:
# ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10
RTNETLINK answers: Bad address
and in dmesg (with bnx2x.debug=0x20):
bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN
configuration the interface is down
Other drivers have no problem with this.
Fix this peculiar behavior in the following way:
- Accept requests to add/kill VID regardless of the device state.
Maintain the requested list of VIDs in the bp->vlan_reg list.
- If the device is up, try to configure the VID list into the hardware.
If we run out of VLAN credits or encounter a failure configuring an
entry, fall back to accepting all VLANs.
If we successfully configure all entries from the list, turn the
fallback off.
- Use the same code for reconfiguring VLANs during NIC load.
Have to change the signed-off-by line to avoid spam to original people.
