Subject: wpa_supplicant: Fix HT STBC capability overriding on big-endian CPUs
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4fd90f61df3f832449e5e5a1bd074188087bbbe0;p=thirdparty%2Fhostap.git

wpa_supplicant: Fix HT STBC capability overriding on big-endian CPUs

The STBC bits need to be converted to little-endian just like the mask
they are ANDed with.

Fixes: cdeea70f59d0 ("wpa_supplicant: Allow overriding HT STBC capabilities")
