Currently, the second bridge command overwrites the first one.
Fix this by adding this VID to the interface behind $swp2.
The one_bridge_two_pvids() test intends to check that there is no

PVID VLAN.

Minimal test for guest_memfd to test that when memory is marked shared
in a VM, the host can read and write to it via an mmap()ed address,
and the guest can also read and write to it.

Test using guest_memfd from userspace, since guest_memfd now has
mmap() support.
Tests:
1. mmap() should now always return a valid address
2. Test that madvise() doesn't give any issues when pages are not
faulted in.
3. Test that pages should not be faultable before association w
Using HugeTLB as the huge page allocator for guest_memfd allows reuse
of HugeTLB's reporting mechanism.

We use a well known VID/PID on a driver that doesn't need to talk to
the device, ensures we created the device against the target driver,
then load our program and ensure we have unbound to this driver and use
hid-generic instead.

which prevented certain pins from having their bias configured.
