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: https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath10k/ath10k-fwencoder 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 */ ATH10K_FW_FEATURE_EXT_WMI_MGMT_RX = 0, /* Firmware from 10X branch. Deprecated, don't use in new code. */ ATH10K_FW_FEATURE_WMI_10X = 1, [...] 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. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
