From: Ezequiel Garcia 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.
