Build error seen with Linux kernel 5.0 and
when CONFIG_RTE_KNI_KMOD_ETHTOOL is enabled.

build error:
.../build/build/kernel/linux/kni/ixgbe_ethtool.c:1746:4:
  error: too few arguments to function ‘dev_open’
    dev_open(netdev);
    ^~~~~~~~

.../linux/linux/include/linux/netdevice.h:2620:5: note: declared here
 int dev_open(struct net_device *dev, struct netlink_ext_ack *extack);
     ^~~~~~~~

     ^~~~~~~~

dev_open() is changed in Linux kernel version 5.0 and now requires
a new parameter, 'struct netlink_ext_ack *extack'.
Fixed by defining dev_open as macro when 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.

Off the topic.

This is the patch 50000 in patchwork! This is a big number.
Thanks everyone contributed!

https://patches.dpdk.org/patch/50000/

The historical numbers from DPDK patchwork:
50000 - Jan. 22, 2019 (253 days) [ 8 months, 8 days / 36 weeks and 1 day ]
40000 - May. 14, 2018 (217 days)
30000 - Oct. 9, 2017 (258 days)
20000 - Jan. 25, 2017 (372 days)
10000 - Jan. 20, 2016 (645 days)
00001 - April 16, 2014


This is the first time DPDK patch pace slowed down (slightly), I guess this is
because of the holidays in the middle and small 19.02, but I think next
milestone which includes 19.05 will clarify this.

Series applied, thanks
and congratulations for the patch 50000.
I suspect you were waiting for posting it at the right time :)
