Subject: hostapd: enable STBC only for STBC capable STAs
|
|
X-Git-Url: http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=commitdiff_plain;h=36af1c7d31bdc5ba4dacacbf32d3c7585665ae2b

hostapd: enable STBC only for STBC capable STAs
|
|
|
|
hostapd simply used its own STBC configuration in the STA's HT caps. This
|
|
resulted in TX STBC being used for STAs not supporting RX STBC, which in
|
|
turn resulted in the STA not receiving anything.
|
|
|
|
Fix this by handling the STBC flags in the same way mac80211 does. Mask
|
|
out RX STBC if we don't support TX STBC and vice versa.
|
|
|
|
Tested only with the nl80211 driver and a STBC incapable STA.
