> This patch adds support for ECMP hash policy choice via a new sysctl > called fib_multipath_hash_policy and also adds support for L4 hashes. > The current values for fib_multipath_hash_policy are: > 0 - layer 3 (default) > 1 - layer 4 > If there's an skb hash already set and it matches the chosen policy then it > will be used instead of being calculated (currently only for L4). > In L3 mode we always calculate the hash due to the ICMP error special > case, the flow dissector's field consistentification should handle the > address order thus we can remove the address reversals. > If the skb is provided we always use it for the hash calculation, > otherwise we fallback to fl4, that is if skb is NULL fl4 has to be set. > > Signed-off-by: Nikolay Aleksandrov <niko...@cumulusnetworks.com> Applied, thanks Nikolay.
