gve: Flow steering trigger reset only for timeout error

2024-11-15T23:36:59Z

When configuring flow steering rules, the driver is currently going through a reset for all errors from the device. Instead, the driver should only reset when there's a timeout error from the device.

gve: change to use page_pool_put_full_page when recycling pages

2024-10-31T00:59:16Z

The driver currently uses page_pool_put_page() to recycle page pool pages. Since gve uses split pages, if the fragment being recycled is not the last fragment in the page, there is no dma sync operation. When the last fragment is recycled, dma sync is performed by page pool infra according to the value passed as dma_sync_size which right now is set to the size of fragment. But the correct thing to do is to dma sync the entire page when the last fragment is recycled. Hence change to using page_pool_put_full_page().

gve: add support for basic queue stats

2024-10-16T01:50:10Z

Implement netdev_stats_ops to export basic per-queue stats. With page pool support for DQO added in the previous patches, rx-alloc-fail captures failures in page pool allocations as well since the rx_buf_alloc_fail stat tracked in the driver is incremented when gve_alloc_buffer returns error.

gve: adopt page pool for DQ RDA mode

2024-10-16T01:50:10Z

For DQ queue format in raw DMA addressing(RDA) mode, implement page pool recycling of buffers by leveraging a few helper functions. DQ QPL mode will continue to use the exisiting recycling logic. This is because in QPL mode, the pages come from a constant set of pages that the driver pre-allocates and registers with the device.
