From: Ariel Levkovich <lariel@xxxxxxxxxxxx>
Add ib_uverbs_flow_spec_mpls to define the rule to match MPLS
protocol.
The spec includes the generic specs header, type, size and reserved
fields while the filter itself is defined as ib_uverbs_flow_mpls_filter
and includes a single 32bit field named 'label' which consists of:
Bits 0:19 - The MPLS label.
Bits 20:22 - Traffic class field.
Bit 23 - Bottom of stack bit.
Bits 24:31 - Time to live (TTL) field.
