Subject: [PATCH net-next 0/2] Improvements to the DSA deferred xmit
Date: Fri, 27 Dec 2019 03:42:06 +0200 [thread overview]
Message-ID: <20191227014208.7189-1-olteanv@gmail.com> (raw)
The DSA deferred xmit mechanism is currently used by a single driver
(sja1105) because the transmission of some operations requires SPI
access in the fastpath.
This 2-patch series makes this mechanism better for everybody:
- For those who don't use it, thanks to one less assignment in the
hotpath
- For those who do, by making its scheduling more amenable and moving it
outside the generic workqueue (since it still deals with packet
hotpath, after all)
