| * csrConvertPhyCBStateToIniValue have been |
| * introduced to convert the ini value to the ENUM used in csr and MAC for CB state |
| * Ideally we should have kept the ini value and enum value same and representing the same |
| * cb values as in 11n standard i.e. |
| * Set to 1 (SCA) if the secondary channel is above the primary channel |
| * Set to 3 (SCB) if the secondary channel is below the primary channel |
| * Set to 0 (SCN) if no secondary channel is present |
| * However, since our driver is already distributed we will keep the ini definition as it is which is: |
| * 0 - secondary none |
| * 1 - secondary LOW |
| * 2 - secondary HIGH |
| * and convert to enum value used within the driver in |
| * csrChangeDefaultConfigParam using this function |
| * The enum values are as follows: |
| * PHY_SINGLE_CHANNEL_CENTERED = 0 |
| * PHY_DOUBLE_CHANNEL_LOW_PRIMARY = 1 |
| * PHY_DOUBLE_CHANNEL_HIGH_PRIMARY = 3 |
