H A Ddevlink-port.rst39 subfunction (SF).
331 Subfunction section in Maximum IO events queues setup
334 Subfunction is a lightweight function that has a parent PCI function on which
335 it is deployed. Subfunction is created and deployed in unit of 1. Unlike
336 SRIOV VFs, a subfunction doesn't require its own PCI virtual function.
337 A subfunction communicates with the hardware through the parent PCI function.
339 To use a subfunction, 3 steps setup sequence is followed:
341 1) create - create a subfunction;
342 2) configure - configure subfunction attributes;
343 3) deploy - deploy the subfunction;

72 A subfunction has its own function capabilities and its own resources. This
73 means a subfunction has its own dedicated queues (txq, rxq, cq, eq). These
76 When a subfunction is RDMA capable, it has its own QP1, GID table, and RDMA
79 A subfunction has a dedicated window in PCI BAR space that is not shared
