+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')
