Subject: [PATCH net-next v2 0/2] net: ethernet: mtk_eth_soc: improve RX performance
Date: Mon, 29 Jul 2024 21:29:53 +0300 [thread overview]
Message-ID: <20240729183038.1959-1-eladwf@gmail.com> (raw)
This small series includes two short and simple patches to improve RX performance
on this driver.

About 16% more packets/sec without XDP program loaded,
and about 5% more packets/sec when using PP.
Tested on Banana Pi BPI-R4 (MT7988A)

Technically, this is version 2 of the “use prefetch methods” patch.
Initially, I submitted it as a single patch for review (RFC),
but later I decided to include a second patch, resulting in this series
Changes in v2:
- Add "use PP exclusively for XDP programs" patch and create this series
