Because we can miss AP wakeup (beacon) while scanning other channels,
it's better go into wakeup state and inform the AP of that upon
returning to the operating channel, rather than staying asleep and
waiting for the next TIM indicating traffic for us.
This saves precious time, especially when we only have 200ms inter-
scan period for monitoring the active connection.

firmware will disable the ethernet link on the other port. Firmware

It will be necessary to update more than one field in the link_info

merely translating ethtool speed values to firmware speed values,
change the responsiblity of this function to update all the necessary
link_info fields required to force the speed change to the desired
ethtool value. This also reduces code duplication somewhat at the two
call sites, which otherwise both have to independently update link_info
fields to turn off auto negotiation advertisements.
Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen
to have the same values, but req_link_speed is utilimately passed as

mlxsw: Expose transceiver overheat counter
Amit says:
An overheated transceiver can be the root cause of various network
problems such as link flapping. Counting the number of times a
transceiver's temperature was higher than its configured threshold can
therefore help in debugging such issues.
This patch set exposes a transceiver overheat counter via ethtool. This
is achieved by configuring the Spectrum ASIC to generate events whenever
a transceiver is overheated. The temperature thresholds are queried from
the transceiver (if available) and set to the default otherwise.
Example:
...
transceiver_overheat: 2
Patch set overview:
Patches #1-#3 add required device registers
Patches #4-#5 add required infrastructure in mlxsw to configure and
count overheat events
Patches #6-#9 gradually add support for the transceiver overheat counter

Generic adjustment for flow dissector in DSA
This is the v2 of a series initially submitted in May:
https://www.spinics.net/lists/netdev/msg651866.html
The end goal is to get rid of the unintuitive code for the flow
dissector that currently exists in the taggers. It can all be replaced
by a single, common function.
Some background work needs to be done for that. Especially the ocelot
driver poses some problems, since it has a different tag length between
RX and TX, and I didn't want to make DSA aware of that, since I could
instead make the tag lengths equal.
Changes in v3:
- Added an optimization (08/15) that makes the generic case not need to
call the .flow_dissect function pointer. Basically .flow_dissect now
currently only exists for sja1105.
- Moved the .promisc_on_master property to the tagger structure.
- Added the .tail_tag property to the tagger structure.
- Disabled "suppresscc = all" from my .gitconfig.
