Subject: Define a QCA vendor command to validate encryption engine
X-Git-Tag: hostap_2_6~46
X-Git-Url: http://www.project-moonshot.org/gitweb/?p=mech_eap.git;a=commitdiff_plain;h=0d7eba5417cf0caa42d72ec3acbfe9b068d06e66

Define a QCA vendor command to validate encryption engine

This command carries 802.11 header and payload along with key (TK) and
PN for encryption/decryption purpose. Firmware/driver encrypts/decrypts
the given data and sends to userspace as a response to the command. User
space component can validate the data received from the driver to unit
test the hardware's encryption engine.
