Declaration is '.. c:function:: void ieee80211_tx_status (struct ieee80211_hw *hw, struct sk_buff *skb)'. This is because there's a function named ieee80211_tx_status() and a struct named ieee80211_tx_status. This has been discussed previously but no solution found: https://lore.kernel.org/all/20220521114629.6ee9fc06@coco.lan/ There's also a bug open for three years with no solution in sight: https://github.com/sphinx-doc/sphinx/pull/8313 So I guess we have no other solution than to a workaround this in the code, for example to rename the function to ieee80211_tx_status_skb() to avoid the name conflict. I got the idea for the name from ieee80211_tx_status_noskb() in which the skb is not provided as an argument, instead with ieee80211_tx_status_skb() the skb is provided. Compile tested only.
