Subject: [PATCH 9/15] rt2x00: Split EEPROM_NIC_TX_RX_FIXED
Date: Sat, 20 Dec 2008 10:57:47 +0100	[thread overview]
Message-ID: <200812201057.47712.IvDoorn@gmail.com> (raw)
In-Reply-To: <200812201057.02583.IvDoorn@gmail.com>

The 2 bits in EEPROM_NIC_TX_RX_FIXED each influence
a different antenna. We might as well split the
definition and directly read the correct bit.
