Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.
For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.
This patch now increases the maxmimum frame size from 1528 to 1656
bytes.

@Kalle, I saw that this patch was marked as deferred [1] but I couldn't find
any mail why it was done so. It seems like this currently creates real world
problems - so would be nice if you could explain shortly what is currently
blocking its acceptance.
Ping?
Sorry for the delay, my plan was to first write some documentation about
different hardware families but haven't managed to do that yet.
My problem with this patch is that I don't know what hardware and
firmware versions were tested, so it needs analysis before I feel safe
to apply it. The ath10k hardware families are very different that even
if a patch works perfectly on one ath10k hardware it could still break
badly on another one.
What makes me faster to apply ath10k patches is to have comprehensive
analysis in the commit log. This shows me the patch author has
considered about all hardware families, not just the one he is testing
on, and that I don't need to do the analysis myself.
It has been in ath10k-ct for a while, and that has some fairly wide coverage
in OpenWrt, so likely if there were problems we would have seen it already.
I did not make any specific changes to firmware to support this, so upstream
firmware should behave similarly.
Seems like upstream ath10k could really benefit from having some test beds
so you can actually test code on different chips and have confidence
in your changes!
Thanks,
Ben
