Ilias Apalodimas 495de55f70 net: netsec: Add support for XDP frame size ... This driver takes advantage of page_pool PP_FLAG_DMA_SYNC_DEV that can help reduce the number of cache-lines that need to be flushed when doing DMA sync for_device. Due to xdp_adjust_tail can grow the area accessible to the by the CPU (can possibly write into), then max sync length *after* bpf_prog_run_xdp() needs to be taken into account. For XDP_TX action the driver is smart and does DMA-sync. When growing tail this is still safe, because page_pool have DMA-mapped the entire page size.
