Subject: [PATCH net-next v2 0/7] Polling be gone on LAN95xx

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
