It can read-modify-write the advertised field: if (ipcnfg & E1000_IPCNFG_EEE_100M_AN) 2594 edata->advertised |= ADVERTISED_100baseT_Full; This is ok for the normal ethtool eee_get call, which always zeroes the input data before. But eee_set_cur also calls eee_get_cur and it did not zero the input field. Later on it then compares agsinst the field, which can contain partial stack garbage. Zero the input field in eee_set_cur() too. Cc: jeffrey.t.kirsher@intel.com Cc: netdev@vger.kernel.org Signed-off-by: Andi Kleen Acked-by: Jeff Kirsher Signed-off-by: David S.
