Merge tag 'net-6.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni: "Including fixes from can, bluetooth and ipsec. This contains a last minute revert of a recent GRE patch, mostly to allow me stating there are no known regressions outstanding. Current release - regressions: - revert "gre: Fix IPv6 link-local address generation." - eth: ti: am65-cpsw: fix NAPI registration sequence Previous releases - regressions: - ipv6: fix memleak of nhc_pcpu_rth_output in fib_check_nh_v6_gw(). - mptcp: fix data stream corruption in the address announcement - bluetooth: fix connection regression between LE and non-LE adapters - can: - flexcan: only change CAN state when link up in system PM - ucan: fix out of bound read in strscpy() source Previous releases - always broken: - lwtunnel: fix reentry loops - ipv6: fix TCP GSO segmentation with NAT - xfrm: force software GSO only in tunnel mode - eth: ti: icssg-prueth: add lock to stats Misc: - add Andrea Mayer as a maintainer of SRv6" * tag 'net-6.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (33 commits) MAINTAINERS: Add Andrea Mayer as a maintainer of SRv6 Revert "gre: Fix IPv6 link-local address generation."
