Cover letter [PATCH net 0/2] gre: Reapply IPv6 link-local address generation fix.
Reintroduce the IPv6 link-local address generation fix for GRE and its kernel selftest. These patches were introduced by merge commit b3fc5927de4b ("Merge branch 'gre-fix-regressions-in-ipv6-link-local-address-generation'") but have been reverted by commit 8417db0be5bb ("Merge branch 'gre-revert-ipv6-link-local-address-fix'"), because it uncovered another bug in multipath routing. Now that this bug has been investigated and fixed, we can apply the GRE link-local address fix and its kernel selftest again.
For convenience, here's the original cover letter:
IPv6 link-local address generation has some special cases for GRE devices. This has led to several regressions in the past, and some of them are still not fixed. This series fixes the remaining problems, like the ipv6.conf.<dev>.addr_gen_mode sysctl being ignored and the router discovery process not being started (see details in patch 1).
To avoid any further regressions, patch 2 adds selftests covering IPv4 and IPv6 gre/gretap devices with all combinations of currently supported addr_gen_mode values.
