Subject: [PATCH net-next v3 0/7] Polling be gone on LAN95xx
Date: Thu, 12 May 2022 10:42:00 +0200 [thread overview]
Message-ID: <cover.1652343655.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 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)
