I'm testing these patches on a Linksys AE3000 device which also uses the RT3573
chip. I have an almost complete patch-set which allows me to use the device in
STA and in AP mode, however I still have to resolve a few problems.

Stylistic I would prefer the if outside of if block you included it in.
Something like:
if (tx_chain_num > 2) {
/* Turn on tertiary PAs for 3T devices */
}
if (tx_chain_num > 1) {
/* Turn on secondary PAs for 2T and for 3T devices */
}
/* Turn on primary PAs for 1T, 2T and for 3T devices */
At least to me this is easier to read.
Alternatively it could be changed to a switch statement wit fall-through cases for the number of RX/TX streams.

Ralink 3T chipsets are using a different EEPROM
layout than the others. The EEPROM on these devices
contain more data than the others which does not fit
into 272 byte which the rt2800 driver actually uses.
The Ralink reference driver defines EEPROM_SIZE to
512/1024 bytes for PCI/USB devices respectively.
Increase the EEPROM_SIZE constant to 512 bytes, in
order to make room for EEPROM data of 3T devices.

Looks good to me. However, please resubmit with the typo noticed by Helmut fixed.

Yes it would be more readable. The only disadvantage of separated if statements
is that both conditions will be evaluated on 1T devices.

This sounds more reasonable, I will change the code to use switch statements.

well. Always turn those on if the device uses more
than one tx/rx chains.
