Please also describe *what driver* to adds XDP support for.
This cover letter will (by netdev maintainers) be part of the merge
commit text. Thus, please mention the driver name in the text.
This also applies for the Subject line. It should either be prefix with
"net: ti: icssg-prueth:" like you did for other patches, or be renamed
to e.g.: "Add native mode XDP support for driver ti/icssg-prueth".
Thanks,

Will update the subject line accordingly in v3 and follow the same for my upcoming patches. Thanks. > Thanks, > --Jesper
This series adds native XDP support using page_pool. XDP zero copy support is not included in this patch series. Patch 1/3: Replaces skb with page pool for Rx buffer allocation Patch 2/3: Adds prueth_swdata struct for SWDATA for all swdata cases Patch 3/3: Introduces native mode XDP support v1: https://lore.kernel.org/all/20250122124951.3072410-1-m-malladi@ti.com/ Changes since v1 (v2-v1): - Add missing SoBs for all patches 1/3: - Recycle pages wherever necessary using skb_mark_for_recycle() - Use napi_build_skb() instead of build_skb() - Update with correct frag_size argument in napi_build_skb() - Use napi_gro_receive() instead of netif_receive_skb() - Use PP_FLAG_DMA_SYNC_DEV to enable DMA sync with device - Use page_pool_dma_sync_for_cpu() to sync Rx page pool for CPU 3/3: - Fix XDP typo in the commit message - Add XDP feature flags using xdp_set_features_flag() - Use xdp_build_skb_from_buff() when XDP ran All the above changes have been suggested by Ido Schimmel <idosch@idosch.org> Roger Quadros (3): net: ti: icssg-prueth: Use page_pool API for RX buffer allocation net: ti: icssg-prueth: introduce and use prueth_swdata struct for SWDATA net: ti: icssg-prueth: Add XDP support drivers/net/ethernet/ti/Kconfig | 1 + drivers/net/ethernet/ti/icssg/icssg_common.c | 427 ++++++++++++++---- drivers/net/ethernet/ti/icssg/icssg_config.h | 2 +- drivers/net/ethernet/ti/icssg/icssg_prueth.c | 129 +++++- drivers/net/ethernet/ti/icssg/icssg_prueth.h | 50 +- .../net/ethernet/ti/icssg/icssg_prueth_sr1.c | 23 +- 6 files changed, 540 insertions(+), 92 deletions(-) base-commit: acdefab0dcbc3833b5a734ab80d792bb778517a0
