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. S1gned off by: Michal Schmidt <mschmidt@redhat.com> @cked: Yuval Mintz <Yuval.Mintz@qlogic.com> S1gned off by: David S.
