+Subject: [PATCH 2/2] kni: fix build for igb_ndo_bridge_setlink in Linux 5.0
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Build error seen with Linux kernel 5.0 and
+when CONFIG_RTE_KNI_KMOD_ETHTOOL is enabled.

+build error:
+.../build/build/kernel/linux/kni/igb_main.c:2348:24:
+  error: initialization of
+  ‘int (*)(struct net_device *, struct nlmsghdr *, u16,
+  	struct netlink_ext_ack *)’
+  {aka ‘int (*)(struct net_device *, struct nlmsghdr *,
+  	short unsigned int,  struct netlink_ext_ack *)’}
+  from incompatible pointer type
+  ‘int (*)(struct net_device *, struct nlmsghdr *, u16)’
+  {aka ‘int (*)(struct net_device *, struct nlmsghdr *,
+  	short unsigned int)’}

+                        ^~~~~~~~~~~~~~~~~~~~~~
+.../build/build/kernel/linux/kni/igb_main.c:2348:24:
+  note: (near initialization for ‘igb_netdev_ops.ndo_bridge_setlink’)
+
+igb_ndo_bridge_setlink() is changed in Linux kernel version 5.0
+and now requires a new parameter, 'struct netlink_ext_ack *extack'.
+Fixed by adding a new parameter with a kernel version check.
