With the 2.6.28.1 kernel with attached well-known AP-enable patches on
an x86-64 host with AR5414 hardware, I can get hostapd 0.6.7 running
[1], but both fail to see the network with scans/probes, and fail to
associate with it [1] from a known-good client.
I'm using libnl 1.1 and you can assume that the kernel and hostapd are
logically and well configured; there are no revealing kernel
messages...
Could this relate to bad packet padding or another known issue perhaps?
Let me know what other information could be useful for debugging this
and if [1] is known/expected.
Many thanks!
Daniel

But, only if I configure hostapd to not set the channel. Otherwise, is
it expected I get this?
