81 mapping between a channel index and a PF is fixed, no matter how many channels the user configures.
90 The relation between PF, irq, napi, and queue can be observed via netlink spec::
124 In Rx, the steering tables belong to the primary PF only, and it is its role to distribute incoming

128 In Tx, the primary PF creates a new Tx flow table, which is aliased by the secondaries, so they can
