2025-06-21can: rcar_canfd: Describe channel-specific FD registers using C structGeert Uytterhoeven
The rcar_canfd_f_*() inline functions to obtain channel-specific CAN-FD register offsets really describe a memory layout. Hence replace them by a C structure, to simplify the code, and reduce kernel size. This also gets rid of warnings about unused rcar_canfd_f_*() inline functions, which are reported by recent versions of clang.

2025-06-21gve: add XDP_TX and XDP_REDIRECT support for DQ RDAJoshua Washington
This patch adds support for XDP_TX and XDP_REDIRECT for the DQ RDA queue format. To appropriately support transmission of XDP frames, a new pending packet type GVE_TX_PENDING_PACKET_DQO_XDP_FRAME is introduced for completion handling, as there was a previous assumption that completed packets would be SKBs. XDP_TX handling completes the basic XDP actions, so the feature is recorded accordingly. This patch also enables the ndo_xdp_xmit callback allowing DQ to handle XDP_REDIRECT packets originating from another interface. The XDP spinlock is moved to common TX ring fields so that it can be used in both GQ and DQ. Originally, it was in a section which was mutually exclusive for GQ and DQ. In summary, 3 XDP features are exposed for the DQ RDA queue format: 1) NETDEV_XDP_ACT_BASIC 2) NETDEV_XDP_ACT_NDO_XMIT 3) NETDEV_XDP_ACT_REDIRECT Note that XDP and header-data split are mutually exclusive for the time being due to lack of multi-buffer XDP support. This patch does not add support for the DQ QPL format. That is to come in a future patch series.

2025-06-21gve: refactor DQO TX methods to be more generic for XDPJoshua Washington
This patch performs various minor DQO TX datapath refactors in preparation for adding XDP_TX and XDP_REDIRECT support. The following refactors are performed: 1) gve_tx_fill_pkt_desc_dqo() relies on a SKB pointer to get whether checksum offloading should be enabled. This won't work for the XDP case, which does not have a SKB. This patch updates the method to use a boolean representing whether checksum offloading should be enabled directly. 2) gve_maybe_stop_dqo() contains some synchronization between the true TX head and the cached value, a synchronization which is common for XDP queues and normal netdev queues. However, that method is reserved for netdev TX queues. To avoid duplicate code, this logic is factored out into a new method, gve_has_tx_slots_available(). 3) gve_tx_update_tail() is added to update the TX tail, a functionality that will be common between normal TX and XDP TX codepaths.
