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)
Vladimir Oltean (2): net: dsa: Remove deferred_xmit from dsa_skb_cb net: dsa: Create a kernel thread for each port's deferred xmit work
