Summary
In the mt76 WiFi driver, there is a memory leak when destroying the device. Rx queues have an associated page_pool that is not destroyed in mt76_dma_cleanup, and pages are not returned to the pool when WED is not enabled.
Risk Assessment
Memory leak can exhaust system resources and degrade performance, especially with frequent module load/unload.
Recommendation
Apply the mt76 driver patch that destroys the page_pool in mt76_dma_cleanup and returns pages to the pool when WED is not enabled.
