Dear Support Team,

I am experiencing problems using the qlnxe driver with a QLogic 41000 series
device.

A crash occurs simply by enabling or disabling a VLAN interface created on a
NIC .

I assume that the operation triggers a series of hotplug events raises critical
runs that generates conflicts.

Attached is the crash report.

Best regards
