- 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.
