| Subject: [PATCH] bgmac: Clean warning messages
 | |
| MIME-Version: 1.0
 | |
| Content-Type: text/plain; charset=UTF-8
 | |
| Content-Transfer-Encoding: 8bit
 | |
| 
 | |
| 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.
