This was tested on an system configured with\nmultiple i40e virtual functions. Verified that the MTU was configurable\nand that sending packets greater than the configured MTU resulted in a\ndrop.\n\nSigned-off-by: Michael Bieniek <michaelbieniekdpdk@gmail.com>\n---\n drivers/net/i40e/i40e_ethdev_vf.c | 33 +++++++++++++++++++++++++++++++++\n 1 file changed, 33 insertions(+)",
