sfc: decouple TXQ type from label

2020-09-12T00:15:22Z

Make it possible to have an arbitrary mapping from types to labels, because when we add inner-csum-offload TXQs there will no longer be a convenient nesting hierarchy of NIC types (EF10 will have inner-csum TXQs, while Siena will have HIGHPRI). Correct a misleading comment on efx_hard_start_xmit(). Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: work around TRIGGER_INTERRUPT command not working on SFC9140

2016-08-27T04:43:52Z

MC_CMD_TRIGGER_INTERRUPT does not work on the SFC9140, as used in the sfn7x42q and sfn7x24f. Check for this using the MCDI workaround mechanism. The command is only used during self test. If it's not supported, skip the interrupt test. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: Add MC BISTs to ethtool offline self test on EF10

2013-12-12T22:05:48Z

To run BISTs the MC goes down in to a special mode where it will only respond to MCDI from the testing PF, and TX, RX and event queues are torn down. Other PFs get a message as it goes down to tell them it's going down. When the other PFs get this message, they check the soft status register to tell when the MC has rebooted after BIST mode and they can start recovery.

sfc: Remove extern from function prototypes

2013-09-24T19:52:53Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

sfc: Update copyright banners

Update the dates for files that have been added to in 2012-2013. Drop the 'Solarstorm' brand name that's still lingering here. Signed-off-by: Ben Hutchings

sfc: Run event/IRQ self-test asynchronously when interface is brought up

2012-03-06T18:14:15Z

Generate a test event on each event queue whenever the interface is brought up, then after 1 second check that we have either handled a test event or handled another IRQ for each event queue. Signed-off-by: Ben Hutchings

sfc: Remove dependence on NAPI polling in efx_test_eventq_irq()

2012-01-27T00:10:51Z

We cannot safely assume that the NAPI handler will complete within the 20 ms that we allow for the event self-test. The handler may be deferred for longer than this, particularly on realtime kernels. Instead, check whether either an event has been handled or (as in the old failure path) whether an interrupt has been received and an event has been delivered but not yet handled. Use napi_disable() to synchronize with the NAPI handler before checking, since it will clear events before updating eventq_read_ptr. Remove the test result chan.N.eventq.poll, since it is not an error if the NAPI handler does not run during the test. Signed-off-by: Ben Hutchings

sfc: Move the Solarflare drivers

Moves the Solarflare drivers into drivers/net/ethernet/sfc/ and make the necessary Kconfig and Makefile changes. CC: Steve Hodgson CC: Ben Hutchings Signed-off-by: Jeff Kirsher
