Octeontx2-vf: Fix max packet length errors
Once driver submits the packets to the hardware, each packet
traverse through multiple transmit levels in the following
order:
SMQ -> TL4 -> TL3 -> TL2 -> TL1
The SMQ supports configurable minimum and maximum packet sizes.
It enters to a hang state, if driver submits packets with
out of bound lengths.
To avoid the same, implement packet length validation before
submitting packets to the hardware. Increment tx_dropped counter
on failure.
