Subject: [PATCH] net: mv643xx_eth: Make TSO disabled by default
|
||
|
|
|
||
|
|
Data corruption has been observed to be produced by TSO. For instance,
|
||
|
|
accessing files on a NFS-server with TSO enabled results in different data
|
||
|
|
transferred each time.
|
||
|
|
|
||
|
|
This has been observed only on Kirkwood platforms, i.e. with the mv643xx_eth
|
||
|
|
driver. Same tests on platforms using the mvneta ethernet driver have
|
||
|
|
passed without errors.
|
||
|
|
|
||
|
|
Make TSO disabled by default for now, until we can found a proper fix
|
||
|
|
for the regression.
|
||
|
|
|
||
|
