I'm using the version 2.1 of hostapd, my hostapd.conf alreay included:

country_code=FR
ieee80211d=1
ieee80211h=1

But I thought that I found the problem might be because I didn't get the dfs_cac_time for DFS. I'm using the regulatory database of cfg80211 and in the file  "regdb.c" (which is generated automatically from the database in net/wireless/db.txt) and I always get the dfs_cac_time = 0. For example the in file "regulatory.h" there is a define of REG_RULE_EXT (start, end, bw, gain, eirp, dfs_cac, reg_flags) and in file "regdb.c" I got this line: REG_RULE_EXT(5250, 5330, 80, 0, 20, 0, NL80211_RRF_DFS | 0) and that means my dfs_cac = 0. I'm stucking in how to pass the value for this parameter.
