and-xgbe: remove the abstraction for hwptp

2025-07-21T23:40:15Z

Remove the hwptp abstraction and associated callbacks from the struct xgbe_hw_if {}. The callback structure was only ever assigned a single function, without null checks. This cleanup inlines the logic and moves all the hwtstamp realted code a separate file, improving readability and maintainance.

amd-xgbe: add support for giant packet size

2025-07-02T21:50:07Z

AMD XGBE hardware supports giant Ethernet frames up to 16K bytes. Add support for configuring and enabling giant packet handling in the driver. - Define new register fields and macros for giant packet support. - Update the jumbo frame configuration logic to enable giant packet mode when MTU exceeds the jumbo threshold.

amd-xgbe: add support for new XPCS routines

2025-05-13T11:29:41Z

Add the necessary support to enable Renoir ethernet device. Since the BAR1 address cannot be used to access the XPCS registers on Renoir, use the smn functions. Some of the ethernet add-in-cards have dual PHY but share a single MDIO line (between the ports). In such cases, link inconsistencies are noticed during the heavy traffic and during reboot stress tests. Using smn calls helps avoid such race conditions.

amd-xgbe: reorganize the code of XPCS access

The xgbe_{read/write}_mmd_regs_v* functions have common code which can be moved to helper functions. Add new helper functions to calculate the mmd_address for v1/v2 of xpcs access.

amd-xgbe: Fix to ensure dependent features are toggled with RX checksum offload

2025-04-28T20:59:59Z

According to the XGMAC specification, enabling features such as Layer 3 and Layer 4 Packet Filtering, Split Header and Virtualized Network support automatically selects the IPC Full Checksum Offload Engine on the receive side. When RX checksum offload is disabled, these dependent features must also be disabled to prevent abnormal behavior caused by mismatched feature dependencies. Ensure that toggling RX checksum offload (disabling or enabling) properly disables or enables all dependent features, maintaining consistent and expected behavior in the network device.
