[Xen-API] [XCP1.1] ixgbe jumbo frame support not working

[Christian Fischer <christian.fischer@xxxxxxxxxxxxxxxxxxx>]

I need jumbo frame support. It is not possible to set MTU values above 1504. 
Any hints? ixgbe version 2.1.4 should support a maximum MTU value of 16110.

[root@pool5-icl ~]# ip link set mtu 1505 dev eth5
SIOCSIFMTU: Invalid argument

[root@pool5-icl ~]# lspci | grep 10\ Gigabit
17:00.0 Ethernet controller: Intel Corporation 82599EB 10 Gigabit TN Network 
Connection (rev 01)
17:00.1 Ethernet controller: Intel Corporation 82599EB 10 Gigabit TN Network 
Connection (rev 01)

No problem to set MTU to 9000 for all other network interfaces (Broadcom/Intel 
1GBit).

Thanks
Christian
