Commit Message

Russell King (Oracle) Nov. 21, 2019, 12:36 a.m. UTC 
Rename the mac_link_state() method to mac_pcs_get_state() to make it
clear that it should be returning the MACs PCS current state, which
is used for inband negotiation rather than just reading back what the
MAC has been configured for. Update the documentation to explicitly
mention that this is for inband.

We drop the return value as well; most of phylink doesn't check the
return value and it is not clear what it should do on error - instead
arrange for state->link to be false.

This is something I'd like to do to make it clearer what phylink
expects of this function, and that it shouldn't just read-back how
the MAC was configured.

This version drops the deeper changes, concentrating just on the
phylink API rather than delving deeper into drivers, as I haven't
received any feedback on that patch.

It would be nice to see all these drivers tested with this change.

I'm tempted to just apply this, any objections?

Russell, which of this patch or: http://patchwork.ozlabs.org/patch/1197425/

would you consider worthy of merging?

Let's go with v2 for now - it gets the rename done with less risk that
there'll be a problem.  I can always do the remainder in a separate
patch after the merge window as a separate patch.

Florian, I assume you asked because you wanted to do some testing?
Please let me know if you need more time, otherwise I'll apply this
later today.

Please go ahead, if there are issues we can always follow-up. Thanks.

Applied to net-next now, thank you!
