At least for me, this is more than enough. Thanks.

I don't have the setup at the moment to test it again - maybe Issam can do
this. One concern I would have (because I don't find the notes regarding
this problem), is whether this check is now breaking because we count
more things. In the past, rxlp/rxok was used for the check. And now I
don't know whether the count for the other ones were still increasing.

* RXHP (rather sure that "high priority frame" wasn't increasing)
* RXEOL ("no RX descriptors available" - I would guess no, but I can't say
for>
   sure)

* RXORN ("FIFO overrun" I would guess no, but I can't say for sure)

Great, thanks for the review! I'll let it sit in patchwork for a little
while to give people a chance to test it out before sending it over to
Kalle to be applied :)

Hi Toke,

this looks good to me in general. I'm not sure either about the particular RX
interrupts. We can test this by putting the AP in a shield box and verify that
the counters are actually increasing, and that should be good enough.

Thank you!

Hi Toke,

I have tested this patch in mesh mode, and it functions as expected.

I conducted the test by placing one node inside a shield box and the other outside, then verified whether a reset occurred due to RX path inactivity.
