This patch will also need to update kmod-crypto-ctr to depend on kmod-crypto-iv since the ctr module relies on the chainiv module (line 228 in linux-3.18 after patches in OpenWRT). I’ve been looking at the cryptoapi ports for mac80211 and figured this out when I was getting a “file not found” error from hostapd which traced back to the chainiv module not being found.
