rG9d4823824d40: gve: Disallow MTUs within a problematic range
rG909e2d7b691f: gve: Disallow MTUs within a problematic range
Summary

If hardware LRO is enabled with GVE, then setting the driver's MTU to a
range of values around 8000 will cause dropped packets and drastically
degraded performance. While this issue is being investigated, we need
to prohibit the driver's MTU being set to a value within this range.
