   3 Subject: [PATCH] brcmfmac: Fix station info rate information.
   4
   5 Txrate and rxrate in get_station got assigned first with value
   6 in kbps and then divided by 100 to get it in 100kbps unit. The
   7 problem with that is that type of rate is u16 which resulted
   8 in incorrect values for high data rate values.
