new CHECK: PowerLinux - MTU=9000 and 10G speed and TSO=on

[PeterPitterling]

at least 1 ethX device should have MTU=9000 and 10G speed

• [ ] tcp-segmentation-offload -->tso == "on"
• [ ] MTU --> mtu = 9000
• [ ] 10G linkspeed

tso = eth["tcp-segmentation-offload"]
if tso == "off":
  tso_warning = 1
