Subject: [dpdk-dev] [PATCH 2/2] net/bonding: fix MAC address when one port resets
Date: Tue, 25 Feb 2020 17:29:03 +0800
Message-ID: <20200225092903.38455-3-huwei013@chinasoftinc.com> (raw)
In-Reply-To: <20200225092903.38455-1-huwei013@chinasoftinc.com>

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

Currently, based on a active-backup bond device, in the following 2 cases:
1) The primary port resets. The link status of the primary port changes
   from up to down.
2) When switching the active port, one slave port resets at the same time.
one slave port changes to the primary port, but the new primary port's MAC
address probably cannot change to the bond device's MAC address. And we
can't continue receive packets whose destination MAC addresses are the same
as the bond devices's MAC address.

The current bonding PMD driver call mac_address_slaves_update function to
modify the MAC address of all slaves devices. In mac_address_slaves_update
function, the rte_eth_dev_default_mac_addr_set API function is called to
set the MAC address of the slave devices in turn in the for loop statement.

When one port reset, calling rte_eth_dev_default_mac_addr_set API fails
because the firmware will not respond to the commands from the driver,
and exit the loop, so other slave devices cannot continue to update the
MAC address.

This patch fixes the issue by avoid exiting the loop when calling
rte_eth_dev_default_mac_addr_set fails.
