This is never used, so that doesn't make sense? You probably want to
advertise the max_data_retry_count value contingent on this flag (*) in
some attribute, so that userspace can also detect the presence/absence
of the flag for the feature?
(*) doesn't really need to be contingent on the flag - could just be
contingent on max_data_retry_count being non-zero and then you don't
need the flag.

You already have the attribute, but again, aren't using it.

and if you have these you don't need the WIPHY_FLAG anyway?

min of 0 doesn't make sense, maybe you meant 1? otherwise just don't set
anything here.

This applies to all the patches - please don't break strings across
multiple lines, even if they cross 80 columns. Even checkpatch won't
give you any warning on this.

I guess you should document that -1 means no changes? Not sure how the
IEEE80211_TID_CONF_RETRY comes in, you're always setting it, so that's
useless - better remove that and document that -1 means no changes?
