mac80211: consider WLAN_EID_EXT_HE_OPERATION for parsing CRC
We use the parsing CRC for checking if the beacon changed, and if the WLAN_EID_EXT_HE_OPERATION extended element changes we need to track it so we can react to that. Include it in the CRC calculation. Link: https://lore.kernel.org/r/20200131111300.891737-22-luca@coelho.fi Signed-off-by: Johannes Berg <johannes.berg@intel.com>
