Subject: vxlan: allow a user to set TTL value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afb97186f5d8f1d552298e7423e84c4282e48b92;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

vxlan: allow a user to set TTL value

"ip link add ... type vxlan ... ttl X" allows a user to set the TTL
used by a VXLAN for encapsulation. The provided value was ignored by
vxlan module and the default value of 1 was used when encapsulating
multicast packets.
