Does your USB adapter get an IPv6 address?

Yes, it does.

If you see the problem starts to happen on commit
9514528d92d4cbe086499322370155ed69f5d06c, could you try reverting all
the following commits:
(from new to old)
1eb04e7c9e63 net: reorder all the dst flags
a4c2fd7f7891 net: remove DST_NOCACHE flag
b2a9c0ed75a3 net: remove DST_NOGC flag
5b7c9a8ff828 net: remove dst gc related code
db916649b5dd ipv6: get rid of icmp6 dst garbage collector
587fea741134 ipv6: mark DST_NOGC and remove the operation of dst_free()
ad65a2f05695 ipv6: call dst_hold_safe() properly
9514528d92d4 ipv6: call dst_dev_put() properly

and try if it starts to work?

I'll give that a shot!

Thanks so much for the help! I really appreciate it!
