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:

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)
