This feature will allow setting the MAC address using the VDPA tool. For example, in vdpa_sim_net, the implementation sets the MAC address to the config space. However, for other drivers, they can implement their own function, not limited to the config space. Changelog v2 - Changed the function name to prevent misunderstanding - Added check for blk device - Addressed the comments Changelog v3 - Split the function of the net device from vdpa_nl_cmd_dev_attr_set_doit - Add a lock for the network device's dev_set_attr operation - Address the comments Changelog v4 - Address the comments - Add a lock for the vdap_sim?_net device's dev_set_attr operation Changelog v5 - Address the comments Changelog v6 - Replace all the memcpy of mac address with ether_addr_copy() - Remove the check for VIRTIO_NET_F_MAC in vdpa_dev_net_device_attr_set - Remove unnecessary check - Enhance the error log Changelog v7 - change the code to reverse-xmas tree style - make all patches pass the check of ./scripts/checkpatch.pl --strict - Address other comments Cindy Lu (3): vdpa: support set mac address from vdpa tool vdpa_sim_net: Add the support of set mac address vdpa/mlx5: Add the support of set mac address drivers/vdpa/mlx5/net/mlx5_vnet.c | 28 ++++++++++ drivers/vdpa/vdpa.c | 80 ++++++++++++++++++++++++++++ drivers/vdpa/vdpa_sim/vdpa_sim_net.c | 21 +++++++- include/linux/vdpa.h | 9 ++++ include/uapi/linux/vdpa.h | 1 + 5 files changed, 138 insertions(+), 1 deletion(-)
