Previously, the driver used hardcoded multipliers to determine the number of pages to register for QPLs (e.g., 2x ring size for RX). This rigid approach made it difficult to support larger ring sizes without potentially exceeding the "max_registered_pages" limit reported by the device. The first patch introduces a unified and flexible logic for calculating QPL page requirements. It balances TX and RX page allocations based on the configured ring sizes and scales the total count down proportionally if it would otherwise exceed the device's global registration limit. The second patch leverages this new flexibility to stop ignoring the maximum ring size supported by the device in DQO-QPL mode. Users can now configure ring sizes up to the device-reported maximum, as the driver will automatically adjust the QPL size to stay within allowed memory bounds. ==================== Link: https://patch.msgid.link/20260225182342.1049816-1-joshwash@google.com Signed-off-by: Jakub Kicinski --- eed562b2a6d088d1afa83cd60b2eccaec08e81ca
