- 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.
- Fixes: 3ae8f4e0b98 ('net: mv643xx_eth: Implement software TSO')
