        The commit you reference better to be added as special
tag, eg: Fixes: f8f626754ebe ("ipv6: Move ipv6_find_hdr() out of 
Netfilter code.") before the Signed-off-by line. Then you may skip 
mentioning the commit in the description, it will be in Fixes tag.
Note that the first 12 chars from the commit id are used, not the last.
Second Fixes line can be for 63dca2c0b0e7 ("ipvs: Fix faulty IPv6 
extension header handling in IPVS"). Both Fixes lines should not be

        The Subject line needs to include version and tree,
for example: [PATCHv2 net-next] ipvs: remove v6 dependency on iptables
You increase the version when sending modified patch.

        You can check the Documentation/process/submitting-patches.rst
guide for more info.
