So how do I know that this change doesn't break any other hardware? I
did a quick review and I think it's safe, but the commit log mentions
nothing about this.
the real max rx bundle is decided in ath10k_htc_wait_target.
it is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and the value
reported from firmware.
htc->max_msgs_per_htc_bundle =
min_t(u8, msg->ready_ext.max_msgs_per_htc_bundle,
HTC_HOST_MAX_MSG_PER_RX_BUNDLE);
Please clarify and I can update the commit log.
