3.6.11.2 stable review patch. If anyone has any objections, please let me know. ------------------ From: David Ward [ Upstream commit 4660c7f498c07c43173142ea95145e9dac5a6d14 ] This is needed in order to detect if the timestamp option appears more than once in a packet, to remove the option if the packet is fragmented, etc. My previous change neglected to store the option location when the router addresses were prespecified and Pointer > Length. But now the option location is also stored when Flag is an unrecognized value, to ensure these option handling behaviors are still performed. Signed-off-by: David Ward Signed-off-by: David S.
