Subject: [PATCH net-next v2 0/2] pcnet32: switch to napi_alloc_skb() and napi_gro_receive()
Date: Mon, 25 May 2026 14:54:35 +0200 [thread overview]
Message-ID: <20260525125437.4061-1-oscmaes92@gmail.com> (raw)
Use the newer and more efficient napi_alloc_skb() and napi_gro_receive()
APIs to improve RX throughput.
In my testing this resulted in up to a 25% RX throughput increase in iperf3
tests in both directions.
Changes in v2:
- Clarified why releasing the spinlock during napi_complete_done is legal
