Subject: [PATCH] tg3: Fix DMA allocations on 57766 devices
|
|
|
|
The coherent DMA mask of 31b may not be accepted if
|
|
the DMA mask is configured to use higher memories of
|
|
64b. Set the DMA mask also to lower 32b for 57766
|
|
devices.
|
|
|
|
Fixes: 614f4d166eee ("tg3: Set coherent DMA mask bits to 31 for BCM57766 chipsets")
