Hi all,
Thanks your quick support first!
I did below
1. Update kernel to 3.10.0-123.8.1.el7.x86_64
2. I cherry-pick 4ae2b2c1c4c345d0cb5f5a6b0f20fd6afb4a6962 from branch 2.3,
then generate one patch
3. After install patch, build again, the problem skb_zerocopy solved now,
but still failed for below
Any ideas?
Thanks!

datapath: Add support for RHEL-7 / CentOS-7 kernel.
This patch mostly is related to tunnel API where RHEL 7

extra checks are required to check for parameters of API.
