Subject: iwlwifi: pcie: fix the set of DMA memory mask

From: Sara Sharon <[email protected]>

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.
