Hostapd exits when requesting HT on non HT card?

[Ed W]

Hi, this is a rephrase of a previous question

Is it normal/expected that hostapd will exit with an error if I have a 
config file requesting 802.11n, when the card in question is known not 
to support "n"?  Is there not an argument that hostapd should ignore and 
prefer to continue rather than exit?

For a generic solution it looks like I need to parse details of the card 
in-use and rewrite the conf file appropriately?

Can someone please confirm if this is intended behaviour?

Thanks
