package/ethtool: fix builds for older toolchains

Upstream commit 1fa60003a8b8 made a change to headers that broke
compiles with toolchains using kernel headers prior to 4.11.

Apply the patch slated to address the issue.

+Subject: [PATCH] uapi: Bring in if.h
+
+Bring in if.h from commit eec517cdb481 ("net: Add IF_OPER_TESTING") as
+well as uapi/linux/hdlc/ioctl.h. Ensure that we define all of the
+necessary guards to provide updated definitions of ifmap, ifreq and
+IFNAMSIZ. This resolves build issues with kernel headers < 4.11 which
+lacked 2618be7dccf8739b89e1906b64bd8d551af351e6 ("uapi: fix linux/if.h
+userspace compilation errors").
+
+Fixes: 1fa60003a8b8 ("misc: header includes cleanup")

++ * enum net_device_flags - &struct net_device flags
++ *
++ * These are the &struct net_device flags, they can be set by drivers, the
++ * kernel and some can be triggered by userspace. Userspace can query and
++ * set these flags using userspace utilities but there is also a sysfs
++ * entry available for all dev flags which can be queried and set. These flags
++ * are shared for all types of net_devices. The sysfs entries are available
++ * via /sys/class/net/<dev>/flags. Flags which can be toggled through sysfs
++ * are annotated below, note that only a few flags can be toggled and some
++ * other flags are always preserved from the original net_device flags
++ * even if you try to set them via sysfs. Flags which are always preserved
++ * are kept under the flag grouping @IFF_VOLATILE. Flags which are __volatile__
++ * are annotated below as such.
++ *
++ * You should have a pretty good reason to be extending these flags.
++ *
++ * @IFF_UP: interface is up. Can be toggled through sysfs.
++ * @IFF_BROADCAST: broadcast address valid. Volatile.
++ * @IFF_DEBUG: turn on debugging. Can be toggled through sysfs.
++ * @IFF_LOOPBACK: is a loopback net. Volatile.
++ * @IFF_POINTOPOINT: interface is has p-p link. Volatile.
++ * @IFF_NOTRAILERS: avoid use of trailers. Can be toggled through sysfs.
++ *	Volatile.
++ * @IFF_RUNNING: interface RFC2863 OPER_UP. Volatile.
++ * @IFF_NOARP: no ARP protocol. Can be toggled through sysfs. Volatile.
++ * @IFF_PROMISC: receive all packets. Can be toggled through sysfs.
++ * @IFF_ALLMULTI: receive all multicast packets. Can be toggled through
++ *	sysfs.
++ * @IFF_MASTER: master of a load balancer. Volatile.
++ * @IFF_SLAVE: slave of a load balancer. Volatile.
++ * @IFF_MULTICAST: Supports multicast. Can be toggled through sysfs.
++ * @IFF_PORTSEL: can set media type. Can be toggled through sysfs.
++ * @IFF_AUTOMEDIA: auto media select active. Can be toggled through sysfs.
++ * @IFF_DYNAMIC: dialup device with changing addresses. Can be toggled
++ *	through sysfs.
++ * @IFF_LOWER_UP: driver signals L1 up. Volatile.
