driver/at86rf2xx use luid_get_eui64 to genenerate EUI

[kfessel]

using luid_get_eui64 ensures:

• local admin address bit set
  was done manually before
• group address bit unset
  was done manually before
• count eui up
  was missing
  (luid_get counts up byte 0, the bit changes above make
  LSB and LSB<<1 of byte 0 constant -> 4 addresses are the same)

multiple devices will get the same eui
(since the same luid generation is used in in different drivers
it might happen even though different devices are used)

I can't test this.
I searched for similar problems to PR #13232

[kfessel]

typo fixed

[miri64]

This seem reasonable, however, there are other PRs like this flying around: #12600

[kfessel]

Yes it is a duplicate since while fixing #13232 i searched for the same problem and found it here. #12600 was also a bit stale a that moment, this is only a partial fix for the Problems.

#12600 was also a bit stale a that moment, this is only a partial fix for the Problems.

Last comment 16 days ago I wouldn't consider stale in this community 😅. @maribu @benpicco would you be okay with this going in first when bad comes to worse?

[maribu]

Apparently, this was already fixed as side effect by #13362, which was merged to solve the issue with the collisions of the short addresses in INRIAs testbed.

Then can this be closed?
