So it assumes that the hardware is a 2T3R device. Which is actually incorrect - even though it has three receive radios, it's still a two-stream receive device. >How-To-Repeat: * Bootverbose! * Probe/attach an Intel 4965 * See what's going on! >Fix: Until Intel 3x3 devices are supported, we should limit the TX/RX stream counts to 2. >Release-Note: >Audit-Trail: >Unformatted:
