net: veth: add page_pool for page recycling
Introduce page_pool support in veth driver in order to recycle pages in veth_convert_skb_to_xdp_buff routine and avoid reallocating the skb through the page allocator. The patch has been tested sending tcp traffic to a veth pair where the remote peer is running a simple xdp program just returning xdp_pass: veth upstream codebase: MTU 1500B: ~ 8Gbps MTU 8000B: ~ 13.9Gbps veth upstream codebase + pp support: MTU 1500B: ~ 9.2Gbps MTU 8000B: ~ 16.2Gbps Tested-by: Maryam Tahhan <mtahhan@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
