While the driver reports
ath: TX streams 2, RX streams: 2
in the kernel log (with ATH_DBG_CONFIG set in the debug module parameter), "iw list" only reported
[...] Capabilities: 0x12ce HT20/HT40 SM Power Save disabled RX HT40 SGI TX STBC RX STBC 1-streams [...]
The driver seems to set the value as flag while the iw tool interprets it as number. This patch fixes that.
