vti6: Don't report path MTU below IPV6_MIN_MTU.
[ Upstream commit e3dc847a5f85b43ee2bfc8eae407a7e383483228 ]
In vti6_xmit(), the check for IPV6_MIN_MTU before we
send a ICMPV6_PKT_TOOBIG message is missing. So we might
report a PMTU below 1280. Fix this by adding the required
check.
Fixes: ccd740cbc6e ("vti6: Add pmtu handling to vti6_xmit.")
