Subject: ath10k-ct: reduce memory consumption
|
||
|
|
|
||
|
|
ath10k uses a rather high number of buffers to communicate with the QCA
|
||
|
|
firmware. Especially the HTC (host-target-communication) and HTT
|
||
|
|
(host-target-transport) can take up a lot of memory when data is
|
||
|
|
transferred over a ath10k wifi link.
|
||
|
|
|
||
|
|
This problem was already worked around in commit cc189c0b7fa0 ("mac80211:
|
||
|
|
enable ath10k AHB support for QCA4019") for the ath10k driver from
|
||
|
|
mac80211. But this change was forgotton for the ath10k-ct driver.
