Can you resend the whole series please? Hmm no? Unless I understood things the wrong way, Stefan applied patches 1 to 7 of my v4, and asked me to make a change on the 8th patch. This is v5 just for patch 8/8 of the previous series, I just changed a debug string actually... There was a conflict when he applied it but I believe this is because wpan-next did not contain one of the fixes which made it to Linus' tree a month ago. So in my branch I still have this fix prior to this patch, because otherwise there will be a conflict when merging v6.1-rc1 (which I believe was not done yet). Thanks, Miquèl

But no problem, I'll resent the three "followup" patches in a series. However, the patch for allowing coordinator interfaces should be considered something else, I've sent it to start discussing it as the other patches should not require a lot of review time I guess. I didn't think it made sense to wrap it in the followup series as this is mainly something new, but I'm fine doing it, the first patches can go in while we still discuss it further. > > There was a conflict when he applied it but I believe this is because > > wpan-next did not contain one of the fixes which made it to Linus' tree > > a month ago.

You believe correctly. :-) In my workflow I normally do not merge in changes from net-next until after my latest pull-request was pulled in. I do this to avoid extra merge commits. In case I see a merge conflict in my testing before sending the pull request I add merge guidance to the pull. Which is my plan this time around as well. regards Stefan Schmidt

Do you mean I should drop the fix from my branch and give you a patch which applies on the current wpan-next instead? Thanks, Miquèl

Yes, that is my understanding on rebasing a patch on wpan-next :-) regards Stefan Schmidt

We now have a fine grained filtering information so let's ensure proper filtering in scan mode, which means that only beacons are processed. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> --- Changes in v4: * dev_dbg call with: s/!beacon/non-beacon/. * Rebased on top of wpan-next but there is still a commit that has not been merged (went through a fixes PR), but is already in Linus' tree and was present in my branch when I generated this patch. net/mac802154/rx.c | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-)
