Whoops, sent a fraction of a second too early - this actually causes a
warning too (no idea why four times):
net/mac80211/sta_info.h:560: warning: Incorrect use of kernel-doc format:
* @tx_stats.last_rate: last TX rate
net/mac80211/sta_info.h:560: warning: Incorrect use of kernel-doc format:
* @tx_stats.last_rate: last TX rate
net/mac80211/sta_info.h:560: warning: Incorrect use of kernel-doc format:
* @tx_stats.last_rate: last TX rate
net/mac80211/sta_info.h:560: warning: Incorrect use of kernel-doc format:
* @tx_stats.last_rate: last TX rate
