A better-tested version of kernel and firmware is uploaded now. Looks like I needed to add a hack to firmware to bump pkt-size by 16 for IBSS + RSN encrypted frames. Not sure exactly why, but seems to work in light testing. I removed the skb-padto hack from the kernel, and kernel is rebased on top of official 4.0 now.
