Subject: [PATCH net-next v2 0/7] Polling be gone on LAN95xx
Date: Tue, 3 May 2022 15:15:00 +0200 [thread overview]
Message-ID: <cover.1651574194.git.lukas@wunner.de> (raw)
Do away with link status polling on LAN95xx USB Ethernet
and rely on interrupts instead, thereby reducing bus traffic,
CPU overhead and improving interface bringup latency.
Link to v1:
https://lore.kernel.org/netdev/cover.1651037513.git.lukas@wunner.de/
Changes since v1:
* Patch [4/7]:
* Silence "Error updating MAC full duplex mode" warning if it's
caused by hot-removal. (Oleksij Rempel)
* Explain in commit message why a semicolon on a line by itself is
temporarily added in smsc95xx_status(). (Andrew Lunn)
* Patch [5/7]:
* Eliminate a checkpatch "no space before tabs" warning.
* Explain in commit message why the call to phy_init_hw() is moved
in smsc95xx_resume().
* Patch [6/7]:
* Expand commit message to explain in greater detail why caching the
interrupt mask is beneficial. (Andrew Lunn)
Lukas Wunner (7):
usbnet: Run unregister_netdev() before unbind() again
usbnet: smsc95xx: Don't clear read-only PHY interrupt
usbnet: smsc95xx: Don't reset PHY behind PHY driver's back
usbnet: smsc95xx: Avoid link settings race on interrupt reception
usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid
polling
net: phy: smsc: Cache interrupt mask
net: phy: smsc: Cope with hot-removal in interrupt handler
