Subject: [RFC PATCH net-next 0/2] Add support for Frame preemption (IEEE

Frame Preemption is one of the core standards of TSN. It enables
low latency trasmission of time-critical frames by allowing them to
interrupt the transmission of other non time-critical traffic. Frame
preemption is only active when the link partner is also capable of it.
This negotiation is done using LLDP as specified by the standard. Open
source lldp utilities and other applications, can make use of
the ioctls and the header being here, to query preemption capabilities
and configure various parameters.

Pranavi Somisetty (2):
  include: uapi: Add new ioctl definitions to support Frame Preemption
  include: uapi: Add Frame preemption parameters
