- 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.
