[net-next] net: dsa: felix: convert TAS link speed based on phylink speed

[Xiaoliang Yang]

state->speed holds a value of 10, 100, 1000 or 2500, but
QSYS_TAG_CONFIG_LINK_SPEED expects a value of 0, 1, 2, 3. So convert the
speed to a proper value.

Fixes: de143c0e274b ("net: dsa: felix: Configure Time-Aware Scheduler via
taprio offload")

But next time keep in mind the following:

- The Fixes: tag should never wrap on multiple lines, even if it exceeds
  80 characters.
- Patches that fix a problem in net-next only should go to David's
  net-next tree. Patches that fix a problem on Linus Torvalds' tree
  should go to David's "net" tree. This one should go to "net", not to
  "net-next".
- All tags (Fixes, Signed-off-by, etc) should be grouped together with
  no empty lines between them.

Actually due to the first issue I mentioned, could you please resend
this?

Thanks,
-Vladimir

I modify the commit and resend this patch to "net tree", please reject this one.

Hi Xiaoliang Yang

You dropped "PATCH" from the subject. Please also include a version
number, so it is possible to identify which is the last version:

[PATCH net v2] net: dsa: felix: convert TAS link speed based on phylink speed

https://www.kernel.org/doc/html/latest/process/submitting-patches.html
https://www.kernel.org/doc/html/latest/networking/netdev-FAQ.html

It is a good idea to spend a few minutes every day just reading
patches and review comments to get an idea how the process works.
