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
