# # Configuration for 802.1Q VLAN support # config VLAN_8021Q tristate "802.1Q/802.1ad VLAN Support" ---help--- Select this and you will be able to create 802.1Q VLAN interfaces on your Ethernet interfaces. 802.1Q VLAN supports almost everything a regular Ethernet interface does, including firewalling, bridging, and of course IP traffic. You will need the 'ip' utility in order to effectively use VLANs. See the VLAN web page for more information: To compile this code as a module, choose M here: the module will be called 8021q. If unsure, say N. config VLAN_8021Q_GVRP bool "GVRP (GARP VLAN Registration Protocol) support" depends on VLAN_8021Q select GARP help Select this to enable GVRP end-system support. GVRP is used for automatic propagation of registered VLANs to switches. If unsure, say N. config VLAN_8021Q_MVRP bool "MVRP (Multiple VLAN Registration Protocol) support" depends on VLAN_8021Q select MRP help Select this to enable MVRP end-system support. MVRP is used for automatic propagation of registered VLANs to switches; it supersedes GVRP and is not backwards-compatible.

block: don't try Write Same from __blkdev_issue_zeroout
Write Same can return an error asynchronously if it turns out the underlying SCSI device does not support Write Same, which makes a proper fallback to other methods in __blkdev_issue_zeroout impossible. Thus only issue a Write Same from blkdev_issue_zeroout an don't try it at all from __blkdev_issue_zeroout as a non-invasive workaround.
