It's not just sparse.  gcc will complain too.  But you'll need to
compile for a 64-bit kernel to see it.

WPA2 uses a different IE format.  It is also required to support CCMP,
unlike WPA1, which defaults to TKIP.

I could associate to a WPA1 AP with TKIP, but only on a 32-bit system.
It still fails on the 64-bit system.  wpa_supplicant prints this in a
loop:

RTM_NEWLINK: operstate=0 ifi_flags=0x11003 ([UP][LOWER_UP])
RTM_NEWLINK, IFLA_IFNAME: Interface 'eth1' added
RTM_NEWLINK: operstate=0 ifi_flags=0x11003 ([UP][LOWER_UP])

And the kernel log is:

[ 7729.202964] eth1: New link status: Connected (0001)
[ 7738.072382] eth1: New link status: Disconnected (0002)

[ 7748.527988] eth1: New link status: Disconnected (0002)
[ 7749.683346] eth1: New link status: Connected (0001)
[ 7758.983565] eth1: New link status: Disconnected (0002)

I'm sorry, I'm really limited in time right now to do more tests, and
I'm afraid I'll be mostly offline for the next 3 weeks.
