From 76a771ec4c9adfd75fe53c8505cf656a075d7101 Mon Sep 17 00:00:00 2001 From: Koichiro Den Date: Fri, 6 Dec 2024 10:10:47 +0900 Subject: [PATCH] virtio_net: ensure netdev_tx_reset_queue is called on bind xsk for tx virtnet_sq_bind_xsk_pool() flushes tx skbs and then resets tx queue, so DQL counters need to be reset when flushing has actually occurred, Add virtnet_sq_free_unused_buf_done() as a callback for virtqueue_resize() to handle this.
