From df14cd82752d4472c5ee577425cec047578b92fa Mon Sep 17 00:00:00 2001 From: Guangbin Huang Date: Thu, 18 Nov 2021 20:44:33 +0800 Subject: [PATCH 139/283] net: hns3: PF enable promisc for VF when mac table is overflow mainline inclusion from mainline-v5.15-rc4 commit 276e60421668d019dc655973b1832ea354c0f36c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EMYT CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=276e60421668d019dc655973b1832ea354c0f36c ---------------------------------------------------------------------- If unicast mac address table is full, and user add a new mac address, the unicast promisc needs to be enabled for the new unicast mac address can be used. So does the multicast promisc. Now this feature has been implemented for PF, and VF should be implemented too. When the mac table of VF is overflow, PF will enable promisc for this VF.
