X-Git-Tag: v2.6.32-rc1~703^2~367^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=57ef5ddb456649667438e023f67dd3a3ff3fbed8;p=profile%2Fivi%2Fkernel-x86-ivi.git mac80211: Mark a destination sequence number as valid when a PREQ is received. If a PREQ frame is received giving us a fresher DSN than what we have, record the new dsn and mark it as valid. This patch fixes a bug in the setting of the MESH_PATH_DSN_VALID flag. Also, minor fix to coding style on that file. Signed-off-by: Javier Cardona Signed-off-by: John W.
