Simon Horman, linux-kernel
Test that ICMP error messages generated by an IPsec gateway use
the correct source address (the gateway's address, not the
unreachable destination).
Signed-off-by: Antony Antony <antony.antony@secunet.com>
---
v1->v2 : add kernel selftest script
v2->v3 : fix test script. The IFS, space, got mangled.
v3->v4 : added MTU tests
- fix test script based on reviews
