Hi Johannes!

does it make live easier when we use in-line member comments:

 https://www.kernel.org/doc/html/latest/doc-guide/kernel-doc.html#in-line-member-documentation-comments

and place the entire list in a literalblock? 

This is what I (sloppy) tested :


      void (*reset_tsf)(struct ieee80211_hw *hw, struct ieee80211_vif *vif);
       int (*tx_last_beacon)(struct ieee80211_hw *hw);

       /**
        * @ampdu_action: Perform a certain A-MPDU action
        *
        * The RA/TID combination determines the destination and TID we want
        * the ampdu action to be performed for. The action is defined through
        * ieee80211_ampdu_mlme_action.
        * When the action is set to %IEEE80211_AMPDU_TX_OPERATIONAL the driver
        * may neither send aggregates containing more subframes than @buf_size
        * nor send aggregates in a way that lost frames would exceed the
        * buffer size. If just limiting the aggregate size, this would be
        * possible with a buf_size of 8::
        *
        *   - TX: 1.....7
        *   - RX:  2....7 (lost frame #1)
        *   - TX:        8..1...
        *
        * which is invalid since #1 was now re-transmitted well past the
        * buffer size of 8. Correct ways to retransmit #1 would be::
        *
        *   - TX:       1 or 18 or 81
        *
        * Even "189" would be wrong since 1 could be lost again.
        *
        * Returns a negative error code on failure.
        * The callback can sleep.
        */

       int (*ampdu_action)(struct ieee80211_hw *hw,
                           struct ieee80211_vif *vif,
                           struct ieee80211_ampdu_params *params);

just my 2cent.
