Subject: [PATCH net] rename RTNH_F_EXTERNAL to RTNH_F_OFFLOAD

From: Roopa Prabhu <roopa@...ulusnetworks.com>

RTNH_F_EXTERNAL today is printed as "offload" in iproute2 output.

This patch renames the flag to be consistent with what the user sees.

Signed-off-by: Roopa Prabhu <roopa@...ulusnetworks.com>

RTNH_F_EXTERNAL was introduced in 4.1 and is not out in 4.0 kernel.
