From 93b1b31f87ae7c0795afc7586d28f3ed4f859d20 Mon Sep 17 00:00:00 2001 From: Tonghao Zhang Date: Wed, 2 Aug 2017 09:34:15 -0700 Subject: ipv4: Introduce ipip_offload_init helper function. It's convenient to init ipip offload. We will check the return value, and print KERN_CRIT info on failure. Signed-off-by: Tonghao Zhang Signed-off-by: David S.
