This is a note to let you know that I've just added the patch titled iavf: Fix failure to exit out from last all-multicast mode to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: iavf-fix-failure-to-exit-out-from-last-all-multicast.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 3a9d3d0dc8b580d93a9cf7c527d22aee9e171abf Author: Piotr Marczak <piotr.marczak@xxxxxxxxx> Date: Fri Jun 4 09:48:56 2021 -0700 iavf: Fix failure to exit out from last all-multicast mode [ Upstream commit 8905072a192fffe9389255489db250c73ecab008 ] The driver could only quit allmulti when allmulti and promisc modes are turn on at the same time. If promisc had been off there was no way to turn off allmulti mode. The patch corrects this behavior. Switching allmulti does not depends on promisc state mode anymore Fixes: f42a5c74da99 ("i40e: Add allmulti support for the VF") Signed-off-by: Piotr Marczak <piotr.marczak@xxxxxxxxx> Tested-by: Tony Brelinski <tony.brelinski@xxxxxxxxx> Signed-off-by: Tony Nguyen <anthony.l.nguyen@xxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/net/ethernet/intel/iavf/iavf_main.c b/drivers/net/ethernet/intel/iavf/iavf_main.c index c7e365267bc0f..43afe887cac9e 100644 --- a/drivers/net/ethernet/intel/iavf/iavf_main.c +++ b/drivers/net/ethernet/intel/iavf/iavf_main.c @@ -1626,8 +1626,7 @@ static int iavf_process_aq_command(struct iavf_adapter *adapter) iavf_set_promiscuous(adapter, FLAG_VF_MULTICAST_PROMISC); return 0; } - - if ((adapter->aq_required & IAVF_FLAG_AQ_RELEASE_PROMISC) && + if ((adapter->aq_required & IAVF_FLAG_AQ_RELEASE_PROMISC) || (adapter->aq_required & IAVF_FLAG_AQ_RELEASE_ALLMULTI)) { iavf_set_promiscuous(adapter, 0); return 0;
