Corentin Labbe 0a2581cbae wifi: ralink: RT2X00: init EEPROM properly
I have an hostapd setup with a
01:00.0 Network controller: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe

The setup work fine on 6.18.26-gentoo
It breaks on 6.18.33-gentoo (and still broken on 6.18.37)

I found an hint in dmesg:
On 6.18.26-gentoo I see:
May 31 15:48:45 trash01 kernel: ieee80211 phy0: rt2x00_set_rf: Info - RF chipset 0003 detected
On 6.18.33-gentoo I see:
May 31 15:22:57 trash01 kernel: ieee80211 phy0: rt2x00_set_rf: Info - RF chipset 0006 detected

The RF chipset seems badly detected.

The problem was the EEPROM which was badly initialized.
Probably the origin was in some PCI change but unfortunately I couldn't play
to bisect/reboot often the board with this card to do it.
