This is not correct.
The test is against the minimally supported MTU, which should
be 68 not ETH_DATA_LEN which is 1500.

The Hyper-V host doesn't support MTU below 1500. If we try setting MTU to a
value 1500, the host will use 1500 automatically and return 1500 in the

The Hyper-V host doesn't support MTU below 1500. If we try setting MTU
to a
value 1500, the host will use 1500 automatically
