nested structs parsing

[Johannes Berg <johannes@xxxxxxxxxxxxxxxx>]

Hi,

For a while I haven't looked at my documentation for 802.11, and now I
noticed I'm getting warnings due to the nested parsing.

However, something seems to be wrong? I have, for example, this (in
net/mac80211/sta_info.h)

struct sta_info {
	...
        struct {
                u64 packets[IEEE80211_NUM_ACS];
                u64 bytes[IEEE80211_NUM_ACS];
                struct ieee80211_tx_rate last_rate;
                u64 msdu[IEEE80211_NUM_TIDS + 1];
        } tx_stats;
};

but I'm getting the following warnings now, with only "@tx_stats" being
described in the documentation:

net/mac80211/sta_info.h:590: warning: Function parameter or member 'status_stats.last_ack' not described in 'sta_info'
net/mac80211/sta_info.h:590: warning: Function parameter or member 'status_stats.last_ack_signal' not described in 'sta_info'
net/mac80211/sta_info.h:590: warning: Function parameter or member 'status_stats.ack_signal_filled' not described in 'sta_info'
net/mac80211/sta_info.h:590: warning: Function parameter or member 'msdu' not described in 'sta_info'

I can understand the first three of those, but not the last one? Why is
the last one not qualified?

If I change it to this:

        struct {
                u64 packets[IEEE80211_NUM_ACS];
                u64 bytes[IEEE80211_NUM_ACS];
                /**
                 * @last_rate: last TX rate
                 */
                struct ieee80211_tx_rate last_rate;
                /**
                 * @msdu: # of MSDUs per TID
                 */
                u64 msdu[IEEE80211_NUM_TIDS + 1];
        } tx_stats;

I still get a warning on "tx_stats.last_rate", but not on "msdu", which
is sort of obvious from the warning text, but also rather unexpected.

Normally I'd say that the "msdu" warning is originally wrong

However, I'd also argue that if I'm using inline declarations, I
shouldn't have to write it like this:

        struct {
                u64 packets[IEEE80211_NUM_ACS];
                u64 bytes[IEEE80211_NUM_ACS];
                /**
                 * @tx_stats.last_rate: last TX rate
                 */
                struct ieee80211_tx_rate last_rate;
	...
	} tx_stats;

since the comment is contained in the scope of tx_stats already, but
that seems to be what I'd have to do today?

At least fixing one of these to make it consistent would be good :-)

Thanks,
