Originally IWLWIFI versions depend on Kernel versions.see[3]

Since we use a separate mac80211 we should not care about kernel
version - since we use "development"/newest drivers

iwlwifi seems to expect newer firmware too.
- rev. 17 does not seem to be published yet.
- rev. 16 (iwlwifi-7260-16.ucode) is available in linux-firmware[1]
- rev 14,15 are not in mainline linux-firmware but in other repos[2]

Older Firmware is supposed to work with newer drivers according
to iwlwifi documentation[3] - Kernel 3.10+ means that this should
work with later versions too

iwlwifi is a little bit untested on OpenWrt because AP/5GHz issue
on cards. So maybe its a bug with firmware or code itself and
you could report it to the wireless/iwlwifi kernel guys.
See wireless kernel wiki page[4]
