net: qca_spi: Move reset_count to struct qcaspi

2020-01-29T09:21:49Z

[ Upstream commit bc19c32904e36548335b35fdce6ce734e20afc0a ] The reset counter is specific for every QCA700x chip. So move this into the private driver struct. Otherwise we get unpredictable reset behavior in setups with multiple QCA700x chips.

net: qca_spi: Make sure the QCA7000 reset is triggered

2018-08-24T11:27:00Z

[ Upstream commit 711c62dfa6bdb4326ca6c587f295ea5c4f7269de ] In case the SPI thread is not running, a simple reset of sync state won't fix the transmit timeout. We also need to wake up the kernel thread. Signed-off-by: Stefan Wahren Fixes: ed7d42e24eff ("net: qca_spi: fix transmit queue timeout handling") Signed-off-by: David S.

net: qca_spi: Avoid packet drop during initial sync

2018-08-24T11:27:00Z

[ Upstream commit b2bab426dc715de147f8039a3fccff27d795f4eb ] As long as the synchronization with the QCA7000 isn't finished, we cannot accept packets from the upper layers. So let the SPI thread enable the TX queue after sync and avoid unwanted packet drop.

net: qca_spi: fix transmit queue timeout handling

2015-12-06T17:02:24Z

In case of a tx queue timeout every transmit is blocked until the QCA7000 resets himself and triggers a sync which makes the driver flushs the tx ring. So avoid this blocking situation by triggering the sync immediately after the timeout. Waking the queue doesn't make sense in this situation.

drivers/net: remove all references to obsolete Ethernet-HOWTO

2015-06-23T13:50:35Z

This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller
