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.

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

|
||||
|
||||
On ARM SoCs with bgmac Ethernet hardware we don't have any normal PHY.
|
||||
There is always a switch attached but it's not even controlled over MDIO
|
||||
like in case of MIPS devices.
|
||||
We need a fixed PHY to be able to send/receive packets from the switch.

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.

Subject: [PATCH] bgmac: register fixed PHY for ARM BCM470X / BCM5301X chipsets
|

MIME-Version: 1.0
|

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

Content-Transfer-Encoding: 8bit
|
||||
|
||||
On ARM SoCs with bgmac Ethernet hardware we don't have any normal PHY.
|
||||
There is always a switch attached but it's not even controlled over MDIO
|
||||
like in case of MIPS devices.
|
||||
We need a fixed PHY to be able to send/receive packets from the switch.
