sfc: allow ethtool selftest and MC reboot to complete on an unprivileged function

2015-07-31T22:32:05Z

The policy in the net driver is to attempt MCDI commands and then handle any EPERM error codes appropriately when returned by unprivileged functions. The ethtool selftest contains some tests which are useful on an unprivileged function, such as the event queue interrupt tests, but other tests cannot be performed as the function does not have the required permissions. If a test returns -EPERM, act as though the test was not run and continue. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: Fix memcpy() with const destination compiler warning.

2015-04-17T19:15:40Z

drivers/net/ethernet/sfc/selftest.c: In function ‘efx_iterate_state’: drivers/net/ethernet/sfc/selftest.c:388:9: warning: passing argument 1 of ‘memcpy’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-array-qualifiers] This is because the msg[] member of struct efx_loopback_payload is marked as 'const'. Remove that. Signed-off-by: David S. Miller

sfc: Add support for busy polling

2014-07-23T02:55:20Z

This patch adds the sfc driver code for implementing busy polling. It adds ndo_busy_poll method and locking between it and napi poll. It also adds each napi to the napi_hash right after netif_napi_add(). Uses efx_start_eventq and efx_stop_eventq in the self tests. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: Use ether_addr_copy and eth_broadcast_addr

2014-03-10T17:53:37Z

Faster than memcpy/memset on some architectures. 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. [bwh: Convert the test result to 1 or -1 as for earlier NICs] Signed-off-by: Ben Hutchings

sfc: Update copyright banners

2013-08-29T22:34:51Z

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: Remove efx_process_channel_now()

2013-08-21T18:44:31Z

efx_process_channel_now() is unneeded since self-tests can rely on normal NAPI polling. Remove it and all calls to it. efx_channel::work_pending and efx_channel_processed() are also unneeded (the latter being the same as efx_nic_eventq_read_ack()). Signed-off-by: Ben Hutchings

sfc: lock TX queues when calling netif_device_detach()

2012-12-01T02:37:35Z

The assertion of netif_device_present() at the top of efx_hard_start_xmit() may fail if we don't do this. Signed-off-by: Ben Hutchings

sfc: Fix byte order warning in self-test

2012-12-01T00:26:07Z

Add necessary cast when setting a bogus checksum. Signed-off-by: Ben Hutchings

sfc: Fix loopback self-test with separate_tx_channels=1

2012-10-02T00:58:41Z

The loopback self-test iterates over all the TX queues of channel 0, which is not very interesting when that's an RX-only channel. Signed-off-by: Ben Hutchings
