Subject: [PATCH] bgmac: Clean warning messages
|
|
MIME-Version: 1.0
|

Content-Type: text/plain; charset=UTF-8

On my test environment the throughput of a file transfer drops
|
|
from 4.4MBps to 116KBps due the number of repeated warning
|
|
messages. This patch removes the warning messages as DMA works
|
|
correctly with addresses using 0xC0000000 bits.
