DAN-P (Dual Attached Nodes PRP) nodes are expected to receive
traditional IP packets as well as PRP (Parallel Redundancy
Protocol) tagged (trailer) packets. PRP trailer is 6 bytes
of PRP protocol unit called RCT, Redundancy Control Trailer
(RCT) similar to HSR tag. PRP network can have traditional
Add support for generation of PRP supervision frames. For PRP,
supervision frame format is similar to HSR version 0, but have
a PRP Redundancy Control Trailer (RCT) added and uses a different
message type, PRP_TLV_LIFE_CHECK_DD. Also update
is_supervision_frame() to include the new message type
Parallel Redundancy Protocol (PRP) is another redundancy protocol
introduced by IEC 63439 standard. It is similar to HSR in many
aspects:-
- Use a pair of Ethernet interfaces to created the PRP device
- Use a 6 byte redundancy protocol part (RCT, Redundancy Check
Trailer) similar to HSR Tag.

As a preparatory patch to introduce PRP, refactor the code specific to
handling HSR frames into separate functions and call them through
proto_ops function pointers.

Normally, typical RCU updates would allocate a new piece

The Adreno GPU has the capability to manage its own pagetables and switch
them dynamically from the hardware. To do this the GPU uses TTBR1 for
"global" GPU memory and creates local pagetables for each context and
switches them dynamically with the GPU.

LINE6 drivers create stream URBs with a fixed pipe without checking
its validity, and this may lead to a kernel WARNING at the submission
when a malformed USB descriptor is passed.
For avoiding the kernel warning,
Use the aperture settings from the IOMMU domain to set up the virtual
address range for the GPU. This allows us to transparently deal with
IOMMU side features (like split pagetables).

PASID and PRI capabilities are only enumerated in PF devices. VF devices
do not enumerate these capabilites. IOMMU drivers also need to enumerate
