Subject: [PATCH 2/2] ath10k: move spectral scan support under a separate
|
|
|
|
|
config symbol
|
|
|
|
|
|
|
|
|
|
At the moment, spectral scan support, and with it RELAY, is always enabled
|
|
|
|
|
with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
|
|
|
|
|
RELAY in ath10k, and it unconditionally reserves a relay channel.
|
|
|
|
|
|
|
|
|
|
Having debugfs support in ath10k is often useful even on very small
|
|
|
|
|
embedded routers, where we'd rather like to avoid the code size and RAM
|
|
|
|
|
usage of the relay support. While ath10k-based devices usually have more
|
|
|
|
|
resources than ath9k-based ones, it makes sense to keep the configuration
|
|
|
|
|
symmetric to ath9k, so the same base kernel without RELAY can be used for
|
|
|
|
|
both ath9k and ath10k hardware.
