It seems that, similarly to what happens with MAC registers, they needs to be written with one 16-bit and one 32-bit writes, otherwise the write does not work. The byte write didn't work only on my rtl8185, while it worked on rtl8180 and rtl8187se, BTW since there are probably a number of different ASIC revisions out of there, I let the change to affect all cards. It shouldn't hurt anyway. Signed-off-by: Andrea Merello Signed-off-by: John W.
