-Subject: ath10k: increase rx buffer size to 2048
-
-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.
-
-Tested with two ath10k devices in 802.11s mode, as well as with
-batman-adv on top of 802.11s with forwarding disabled.
-
-Fix originally found and developed by Ben Greear.
