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.
