[dpdk-stable] [PATCH] kni: fix build on RHEL8

[michael.luo at intel.com]

From: Luo Gaoliang <michael.luo at intel.com>

Build error was seen on RHEL8 when CONFIG_RTE_KNI_KMOD_ETHTOOL is enabled.

Build error log:
/root/kni/dpdk-19.05/kernel/linux/kni/ethtool/igb/kcompat.h:3928:25:
error: 'const struct net_device_ops' has no member named 'extended'
 #define ndo_set_vf_vlan extended.ndo_set_vf_vlan
                         ^~~~~~~~

RHEL8 defined ndo_set_vf_vlan in net_device_ops as well as the mainline kernel.
