The comments are indicating the TXMIXER_GAIN_BG and
the TXMIXED_GAIN_A entries are overlapping with the
RSSI_BG2 and RSSI_A2 entries in the extended EEPROM
map. This is not correct, becuase the upper byte of
the RSSI_BG2 and RSSI_A2 entries are reserved. There
are no TX mixer gain values are stored at all in the
extended EEPROM.
Remove the initialization of these entries from the
extended EEPROM map to reflect this.

The TXPOWER_DELTA field of the regular EEPROM
stores the TX power compensation value for HT40.
The extended EEPROM has no such field, it stores
separate TX power values for HT20 and for HT40.

Do you know if this fixes any problems and should be backported to
stable? If any testing can be done on
idVendor 0x148f Ralink Technology, Corp.
idProduct 0x2870 RT2870 Wireless Adapter
please tell me.
With the fixes above,
Acked-by: Paul Menzel <paulepanter@users.sourceforge.net>
Thanks,
Paul

This is a cleanup patch, it does not fix any problem. The removed entries are
not used by the code at all.

The extended EEPROM map is used only for the RT3593 chipset, it does not affect
RT2870 in any way.

Thank you for the review! I will send an updated version.
