From: Robert Stonehouse <rstonehouse@solarflare.com>
The MC firmware is cooperatively multitasking and its scheduler will
send an event when a task yields after running for more than the
expected maximum time. This can be useful for firmware development
but does not usually indicate a serious error and does not help to
detect a lockup (there is a hardware watchdog that does that).
Change the message and reduce log level accordingly.

Not speaking for my employer; that's the marketing department's job.
They asked us to note that Solarflare product names are trademarked.

To: David Miller; +Cc: netdev, linux-net-drivers
From: Jon Cooper <jcooper@solarflare.com>
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]

The addition of RX event merging support means we don't reliably
detect dropped RX events now. Currently we will only detect them if
the previous event for the RX queue had the CONT bit set.
Only accept RX completion events as merged if the
GET_CAPABILITIES_OUT_RX_BATCHING bit is set in datapath_caps (which it
won't be for the low-latency datapath) and the CONT bit is not set on
the event.

We don't directly control RX ingress on Siena or any later
controllers, and so we cannot prevent packets from entering the RX
datapath while the RX queues are not set up. This results in
the hardware incrementing RX_NODESC_DROP_CNT, but it's not an
error and we should not include it in error stats.
When bringing an interface up or down, pull (or wait for) stats and
count the number of packets that were dropped while the interface was
down. Subtract this from the reported RX dropped count.

Split each of efx_mcdi_rpc, efx_mcdi_rpc_finish, and efx_mcdi_rpc_async into
a normal and a _quiet version; made the former log MCDI errors with
netif_err (and include the raw MCDI error code), and the latter never log
them at all. Changed various callers; any where some errors are expected
(but others are not) call the _quiet version and then if necessary log the
MCDI error themselves. Said logging is done by new efx_mcdi_display_error.
Callers of efx_mcdi_rpc*_quiet functions which may want to log the error
need to ensure that their outbuf is big enough to hold an MCDI error; to
this end, they now use MCDI_DECLARE_BUF_OUT_OR_ERR, which always allocates
at least 8 bytes.

efx_flush_all() is a really misleading name - it has nothing to do
with e.g. flushing DMA queues. Since it's called immediately after
efx_stop_port() and is highly dependent on what that does, combine
the two functions.
Update comments to explain what this is doing a little better.
Also update an related and erroneous comment in efx_start_port().

The MC firmware will return error MC_CMD_ERR_ENOSPC if filter
insertion fails due to lack of resources. The net driver's filter
implementation for Falcon-architecture returns EBUSY. They should
behave consistently, so for EF10 change ENOSPC to EBUSY.

We need a dedicated channel on Siena to ensure we can match up
the separate RX and timestamp events for each PTP packet. We won't
do this for EF10 as timestamps are delivered inline.
Pass a channel index of 0 to MC_CMD_PTP_OP_ENABLE when there is no
dedicated channel.

> 6. Improve hardware sensor naming and log messages, from Edward Cree.
> 7. Log all unexpected errors returned by firmware, from Edward Cree.
