Subject: iwlwifi: pcie: fix the set of DMA memory mask
From: Sara Sharon <sara.sharon@intel.com>
commit 2c6262b754f3c3338cb40b23880a3ac1f4693b25 upstream.
Our 9000 device supports 64 bit DMA address for RX only, and
not for TX.
Setting DMA mask to 64 for the whole device is erroneous - we
can do it only for a000 devices where device is capable of
both RX & TX DMA with 64 bit address space.
Fixes: 96a6497bc3ed ("iwlwifi: pcie: add 9000 series multi queue rx DMA support")
