Subject[PATCH] [RFC] ath9k: Fix reporting of RX STBC streams to userspace
Date
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.
