Re: [PATCH net] vxlan: don't allow overwrite of config src addr

When using IPv6 transport and a default dst, a pointer to the configured

configured, then the value is overwritten.

IPv6 route lookup ignores egress ifindex match if the source adress is set,
so if egress ifindex match is desired, the source address must be passed
as any. The overwrite breaks this for subsequent lookups.

Avoid this by copying the configured address to an existing stack variable
and pass a pointer to that instead.

Seems there were another patches applied between the time you created
the patch and sent it and it doesn't apply.

Feel free to add to v2:
