<div>I found iPXE has poor network performance, so I download The EFI drivers from its official website(intel nic <a href="https://downloadcenter.intel.com/download/19186/Intel-Ethernet-Connections-Boot-Utility-Preboot-Images-and-EFI-Drivers">https://downloadcenter.intel.com/download/19186/Intel-Ethernet-Connections-Boot-Utility-Preboot-Images-and-EFI-Drivers</a>.
)</div>
<div>And use chain command to load driver like </div>
<div>chain <span style="background-color: rgba(255, 255, 255, 0);">E<em style="box-sizing: border-box;">nnnn</em>X3.EFI </span>For intel nic</div>
<div>china Rxxxxx.efi. For Realtek nic</div>
<div>and change MTU to 4088</div>
<div><br>
</div>
<div>My tested NIC list:</div>
<div>Intel i210TI</div>
<div>Intel 219v</div>
<div>Realtek GBE<br>

<span>Simply put iPXE does not support larger then 1500 mtu - it would</span><br>
<span>probably require driver rewrites, but for some drivers it might just</span><br>
<span>be to change MTU constants, to know more we need to know which driver</span><br>
<span>you are using.</span><br>
<span></span><br>
<span>One other issue and reason that might mean this will never be</span><br>
<span>implemented is issues with different hardware, for example SNP and</span><br>
<span>UNDI which is setup by Firmware/BIOS/ROM is unlikely to support</span><br>
<span>anything larger then 1500 and for those it mean a inconsistent</span><br>
<span>behavior. Which care is taken to avoid.</span><br>
