I have here vanila v3.8.4 + cpsw patches which were in net-next. As for
the hardware:
[ 0.000000] Machine: Generic AM33XX (Flattened Device Tree), model:
TI AM335x BeagleBone
[ 0.000000] AM335X ES1.0 (neon )
model name : ARMv7 Processor rev 2 (v7l)
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x3
CPU part : 0xc08
CPU revision : 2
If we do have the same hardware and source why do I have different
behavior? Can you send me your .config off-list?
