-Subject: [PATCH ethtool v2 1/3] uapi: Bring in if.h
-Date: Sat, 14 Jan 2023 08:34:09 -0800
-
-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")
-Reported-by: Markus Mayer <mmayer@broadcom.com>
-Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
