Subject: [SCSI] bnx2fc: Validate vlan id in NETDEV_UNREGISTER handler
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=26b2982f78c1fc6f486a67271b1d0a0d305dd54b;p=linux-beck.git

[SCSI] bnx2fc: Validate vlan id in NETDEV_UNREGISTER handler

When bnx2fc receives an UNREGISTER event on a vlan interface it calls
destroy on all interfaces that matches the physical interface. Add
vlan_id check to destroy only the vlan interface that generated the
event.
