Subject: [PATCH net 0/3] net: phy: micrel: Remove latencies support lan8814
Date: Fri, 1 Apr 2022 11:48:02 +0200 [thread overview]
Message-ID: <20220401094805.3343464-1-horatiu.vultur@microchip.com> (raw)
Remove the latencies support both from the PHY driver and from the DT.
The IP already has some default latencies values which can be used to get
decent results. It has the following values(defined in ns):
rx-1000mbit: 429
tx-1000mbit: 201
rx-100mbit: 2346
tx-100mbit: 705
---
But to get better results the following values needs to be set:
rx-1000mbit: 459
tx-1000mbit: 171
rx-100mbit: 1706
tx-100mbit: 1345
We are proposing to use ethtool to set these latencies, the RFC can be found
here[1]
