[dpdk-dev] [PATCH v2] kni: fix build on Centos 7.4 when Ethtool enabled

[Dan Gora]

Fix compilation errors on Centos 7.4 when CONFIG_RTE_KNI_KMOD_ETHTOOL
is set to 'y'.

Centos 7.4 needs HAVE_NDO_BRIDGE_GETLINK_FILTER_MASK_VLAN_FILL:

igb_main.c: In function ‘igb_ndo_bridge_getlink’:
igb_main.c:2289:2: error: too few arguments to function
                   ‘ndo_dflt_bridge_getlink’
  return ndo_dflt_bridge_getlink(skb, pid, seq, dev, mode, 0, 0, nlflags);
  ^

Centos 7.4 needs HAVE_VF_VLAN_PROTO and needs to redefine
ndo_set_vf_vlan to .extended.ndo_set_vf_vlan:

igb_main.c:2318:2: error: unknown field ‘ndo_set_vf_vlan’ specified
                   in initializer
  .ndo_set_vf_vlan = igb_ndo_set_vf_vlan,
  ^
