In some cases, drivers may need to veto the changing of a MAC address on a user port. Such is the case with KSZ9477 when it offloads a HSR device, because it programs the MAC address of multiple ports to a shared hardware register. Those ports need to have equal MAC addresses for the lifetime of the HSR offload. Signed-off-by:

Drivers can provide meaningful error messages which state a reason why they can't perform an offload, and dsa_slave_changeupper() already has the infrastructure to propagate these over netlink rather than printing to the kernel log. So pass the extack argument and modify the xrs700x driver's port_hsr_join() prototype. Also take the opportunity and use the extack for the 2 -EOPNOTSUPP cases from xrs700x_hsr_join(). Signed-off-by:

Add a quirk for a copper SFP that identifies itself as "FS" "SFP-2.5G-T". This module's PHY is inaccessible, and can only run at 2500base-X with the host without negotiation. Add a quirk to enable the 2500base-X interface mode with 2500base-T support and disable auto negotiation. Signed-off-by:

'n_tables' is small, UDP_TUNNEL_NIC_MAX_TABLES = 4 as a maximum. So there is no real point to allocate the 'entries' pointers array with a dedicate memory allocation. Using a flexible array for struct udp_tunnel_nic->entries avoids the overhead of an additional memory allocation. This also saves an indirection when the array is accessed. Finally, __counted_by() can be used for run-time bounds checking if configured and supported by the compiler. Signed-off-by:

As we don't specify the MTU in the driver, the framework will fall back to 1500 bytes and this doesn't work very well when we try to attach a DSA switch: eth1: mtu greater than device maximum ixp4xx_eth c800a000.ethernet eth1: error -22 setting MTU to 1504 to include DSA overhead I checked the developer docs and the hardware can actually do really big frames, so update the driver accordingly.

Eric Dumazet says: ==================== tcp_metrics: four fixes Looking at an inconclusive syzbot report, I was surprised to see that tcp_metrics cache on my host was full of useless entries, even though I have /proc/sys/net/ipv4/tcp_no_metrics_save set to 1.
