iwlwifi: use antenna information in EEPROM
Browse files Browse the repository at this point in the history 
The valid tx/rx antenna information is part of EEPROM, so use it
to configure the device.

For few cases, the EEPROM did not reflect the correct antenna, but
it is too late to modify the EEPROM, so overwrite with .cfg parameters
