When obtaining the firmware capability a buffer is provided of 512 bytes. However, if all features in firmware are supported the buffer needs to be 565 bytes as otherwise truncated information is retrieved from firmware. Increasing the buffer to 768 bytes on stack. Reviewed-by:

Decoding of firmware channel information was not complete for 160MHz support.

Using the NAPI or netdev frag cache along with other drivers can lead to 32 KiB pages being held for a long time, despite only being used for very few page fragments. This can happen if the driver grabs one or two fragments for rx ring refill, while other drivers use (and free up) the remaining fragments. The 32 KiB higher-order page can only be freed once all users have freed their fragments. Depending on the traffic patterns, this can waste a lot of memory and look a lot like a memory leak.
