Subject: [PATCH RFC 1/2] wifi: mac80211: rename ieee80211_tx_status() to ieee80211_tx_status_skb()

From: Kalle Valo <[email protected]>

make htmldocs warns:

Documentation/driver-api/80211/mac80211:109: ./include/net/mac80211.h:5170: WARNING: Duplicate C declaration, also defined at mac80211:1117.
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/[email protected]/

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.
