This is a hack to make cpmac work with the external switch on a DG834 v3; it
|
||
|
|
should also work on other similar routers. It has not been tested on hardware
|
||
|
|
with multiple cpmac devices or with no external switch. It may be safer to
|
||
|
|
move external_switch to pdata rather than trying to detect it, and to set
|
||
|
|
phy_mask correctly rather than moving the phy search loop.
