[PATCH] bcm43xx: OFDM fix for rev 1 cards
Nearly all of the writes to the bcm43xx internal lookup tables (ilt)
involve 16-bit quantities. Accordingly, the ilt_write routine was
coded to pass a u16 value. For one early GPHY chip, 32-bit quantities
are needed. For those writes, the value was clipped to 16 bits. This
patch adds an ilt_write32 routine that receives a 32-bit quantity
and writes it to the appropriate locations.
