Subject: [PATCH net-next v3 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 v2:
https://lore.kernel.org/netdev/cover.1651574194.git.lukas@wunner.de/

Only change since v2:

* Patch [5/7]:
  * Drop call to __irq_enter_raw() which worked around a warning in
    generic_handle_domain_irq().  That warning is gone since
    792ea6a074ae (queued on tip.git/irq/urgent).
    (Marc Zyngier, Thomas Gleixner)


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
