2025-06-13net: stmmac: rk: combine clk_mac_speed rate setting functionsRussell King (Oracle)
rk3568_set_gmac_speed() and rv1126_set_clk_mac_speed() are now identical. Combine these so we have a single copy of this code.

2025-06-13net: stmmac: rk: combine rv1126 set_*_speed() methodsRussell King (Oracle)
Just like rk3568, there is no need to have separate RGMII and RMII methods to set clk_mac_speed() as rgmii_clock() can be used to return the clock rate for both RGMII and RMII interface modes. Combine these two methods.

2025-06-13net: stmmac: rk: add struct for programming register based speedsRussell King (Oracle)
There is a common pattern in the driver where many SoCs need to write a single register with a value dependent on the interface mode and speed. Rather than having a lot of repeated code, add some common functions and a struct to contain the values to be written to a register to select the RGMII and RMII speeds.

2025-06-13net: stmmac: rk: simplify set_*_speed()Russell King (Oracle)
Rather than having lots of regmap_write()s to the same register but with different values depending on the speed, reorganise the functions to use a local variable for the value, and then have one regmap_write() call to write it to the register. This reduces the amount of code and is a step towards further reducing the code size.

2025-06-13net: stmmac: rk: add get_interfaces() implementationRussell King (Oracle)
RK platforms support RGMII and/or RMII depending on the SoC. Detect whether support for a SoC exists by whether the interface specific set_to functions have been populated, and set the appropriate bits in phylink's bitmap of interfaces. This assumes all dwmac interfaces on a SoC have identical support, but it should be noted that this is not true for RK3528 which only supports RGMII on GMAC1. However, the existing code structure permits RGMII to be configured on GMAC0 without complaint, so preserve this behaviour even though it is incorrect to avoid functional change.

2025-06-13net: phy: dp83tg720: switch to adaptive polling and remove random delaysDavid Jander
Now that the PHY reset logic includes a role-specific asymmetric delay to avoid synchronized reset deadlocks, the previously used randomized polling intervals are no longer necessary. This patch removes the get_random_u32_below()-based logic and introduces an adaptive polling strategy: - Fast polling for a short time after link-down - Slow polling if the link remains down - Slower polling when the link is up This balances CPU usage and responsiveness while avoiding reset collisions. Additionally, the driver still relies on polling for all link state changes, as interrupt support is not implemented, and link-up events are not reliably signaled by the PHY. The polling parameters are now documented in the updated top-of-file comment.

Add a .soft_reset callback for the DP83TG720 PHY that issues a hardware reset followed by an asymmetric post-reset delay. The delay differs based on the PHY's master/slave role to avoid synchronized reset deadlocks, which are known to occur when both link partners use identical reset intervals. The delay includes: - a fixed 1ms wait to satisfy MDC access timing per datasheet, and - an empirically chosen extra delay (97ms for master, 149ms for slave).

2025-06-12veth: prevent NULL pointer dereference in veth_xdp_rcvJesper Dangaard Brouer
The veth peer device is RCU protected, but when the peer device gets deleted (veth_dellink) then the pointer is assigned NULL (via RCU_INIT_POINTER). This patch adds a necessary NULL check in veth_xdp_rcv when accessing the veth peer net_device. This fixes a bug introduced in commit dc82a33297fc ("veth: apply qdisc backpressure on full ptr_ring to reduce TX drops"). The bug is a race and only triggers when having inflight packets on a veth that is being deleted.

2025-06-12net: phy: phy_caps: Don't skip better duplex macth on non-exact matchMaxime Chevallier
When performing a non-exact phy_caps lookup, we are looking for a supported mode that matches as closely as possible the passed speed/duplex. Blamed patch broke that logic by returning a match too early in case the caller asks for half-duplex, as a full-duplex linkmode may match first, and returned as a non-exact match without even trying to mach on half-duplex modes.
