From 83c31c9945302cf43fb3d26f5e5b1fecc60a35f1 Mon Sep 17 00:00:00 2001 From: Andrew Rybchenko Date: Tue, 13 Oct 2020 14:45:30 +0100 Subject: [PATCH] net/sfc: implement libefx Tx descs complete event callbacks These callbacks are used when event queue is polled via libefx. The libefx polling is used for management event queue, but we do not expect any Tx complete events on it, and for datapath event queue at flushing.
