Subject: [PATCH net] tun: Fix xdp_rxq_info's queue_index when detaching
Date: Tue, 20 Feb 2024 11:12:07 +0800	[thread overview]
Message-ID: <1708398727-46308-1-git-send-email-wangyunjian@huawei.com> (raw)

When a queue(tfile) is detached, we only update tfile's queue_index,
but do not update xdp_rxq_info's queue_index. This patch fixes it.

Fixes: 8bf5c4ee1889 ("tun: setup xdp_rxq_info")
