EVPN/VXLAN-over-IPv6 and global SRv6 on FRR

[ipspace]

Release notes for release 10.6.0 include

BGP SRv6 unicast at the global (default) VRF

Support has been added for global (default VRF) unicast routing over an SRv6 core -- Global IPv4 over SRv6 Core (RFC 9252), Global IPv6 over SRv6 Core (RFC 9252)

BGP IPv6 VTEP support

Comprehensive IPv6 VTEP support has been added throughout the EVPN codebase. This enables EVPN deployments using IPv6 tunnel endpoints while maintaining full backward compatibility with IPv4 VTEPs.

Let's see whether these features work in practice ;)

A quick test adding evpn.ipv6: True for FRR seems to work (also replacing Arista with FRR in the test)
Test: 41-vxlan-ipv6-bridging.yml

SIP of Networking strikes again: Arista accepts FRR EVPN routes, FRR does not accept Arista's. Have to figure out which one is broken.
