No worries.

I'm meaning the ath10k firmware meta data we have in firmware-N.bin
(N=2,3,4...) file. A quick summary:

Every ath10k firmware release should have firmware-N.bin. The file is
created with this tool:

firmware-N.bin contains various metadata, one of those being firmware
feature flags:

enum ath10k_fw_features {
/* wmi_mgmt_rx_hdr contains extra RSSI information */

/* Firmware from 10X branch. Deprecated, don't use in new code. */


So what you could is add a new flag enum ath10k_fw_features, create a
new firmware-N.bin for your device and enable the flag on the firmware
releases for your device only.

I don't know if this is usable, but one solution which came to my mind.
