From a071bb2a52b01a4e189047192b121a5721105d7a Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Mon, 9 Sep 2024 12:03:56 +0100 Subject: [PATCH] net/iavf: delay VF reset command Commit 0f9ec0cbd2a9 ("net/iavf: fix VF reset when using DCF"), introduced a VF-reset adminq call into the reset sequence for iavf. However, that call was very early in the sequence before other adminq commands had been sent. To delay the VF reset, we can put the message sending in the "dev_close" function, right before the adminq is shut down, and thereby guaranteeing that we won't have any subsequent issues with adminq messages. In the process of making this change, we can also use the iavf_vf_reset function from common/iavf, rather than hard-coding the message sending lower-level calls in the net driver.
