We've had a few internal requests for a way to enable and disable the
hardware VLAN filter at runtime. I'm posting it here for discussion and
to see if anybody else is interested in this feature.
Originally I had planned to do this as an Ethtool ioctl, but decided
instead to handle it through the VLAN module. Ethtool doesn't know
anything about VLANs at all.
There are no userspace changes required to support this functionality.
To disable HW VLAN filtering:
# vconfig set_flag <VLAN interface> 2 1
To enable HW VLAN filtering:
# vconfig set_flag <VLAN interface> 2 0
At this point (somewhat obviously), it's only implemented on e1000, but
this ioctl could be easily implemented by other drivers.
Sounds like a good idea to me.
+ switch (flag) {
+ case VLAN_FLAG_REORDER:
+ if (flag_val)
+ VLAN_DEV_INFO(dev)->flags |= 1;
+ else
+ VLAN_DEV_INFO(dev)->flags &= ~1;
+ break;
If we're defining constants for the flags, might as well use them here
instead of using the bare '1'.
