Add hardware TCP Large Receive Offload (LRO) support to the airoha_eth driver, leveraging the EN7581/AN7583 SoC's 8 dedicated LRO hardware queues mapped to RX queues 24–31. LRO hw offloading does not support Scatter-Gather (SG) so it is required to increase the page_pool allocation order to 2 for RX queues 24–31 (LRO queues). Performance comparison between GRO and hw LRO has been carried out using a 10Gbps NIC: GRO: ~2.7 Gbps LRO: ~8.1 Gbps Tested-by: Madhur Agrawal <madhur.agrawal@airoha.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Link: https://github.com/openwrt/openwrt/pull/23530 Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
