this patch adds a module parameter in order to activate ASPM.
Basically it reapplies d64ec841517a25f6d468bde9f67e5b4cffdc67c7, which
was reverted as some people reported delayed link status detection and
increased boot times: https://lkml.org/lkml/2013/2/6/372.

For a route with IPv6 encapsulation, the traffic class and hop limit
values are interchanged when returned to userspace by the kernel.
For example, see below.

Hi all,
The following program triggers stack-out-of-bounds in tcp_packet. The
kernel version is 4.5 (on Mar 16 commit
