The X540 is a much older network card - around 5 years older than the X710.
From the manual pages:


X540
Bus:      PCIe 2.1 x8
Chipset:  Intel 82598EB
Driver:   ixgbe
Max MTU:  16144
Features: Jumbo Frames, MSIX, TSO & RSS

X710
Bus:      PCIe 3.0 x8
Chipset:  Intel 700-series
Driver:   ixl
Max MTU:  9706
Features: Jumbo Frames, TX/RX checksum offload,
          TSO (TCP Segmentation offload),
          LRO (Large Receive Offload),
          VLAN tag insertion/extraction, VLAN checksum offload,
          VLAN TSO, RSS (Receive Side Steering)

I don't have any X540/ixgbe boards here so can't test that combo unfortunately,
but looking at the feature sets it seems the X540 lacks the LRO feature...
