[tor-relays] Question about new log messages after 0.4.7.7 upgrade

Been getting these syslog messages occasionally *after* the 0.4.7.7 upgrade on my bridge:

-- May 26 21:00:58 torbridge Tor[ ]: Unexpected path length 4 for exit circuit 66 5, purpose 5 [3 similar message(s) suppressed in last 5400 seconds]

May 26 16:26:17 torbridge kernel: [ ] TCP: eth0: Driver has suspect GRO implementation, TCP performance may be compromised. --

Anyone know what they mean and if it's something I should be worried about? Calculated advertised bandwidth seems to be about the same.

For reference, im running latest Raspbian 64-bit Lite on a Raspberry 4 with latest firmware aswell. driver: bcmgenetversion: 5.15.41-v8+
