Thanks for the explanation!
What does this part mean? What is 128 pkts? (I saw that it can be modded by adjusting /sys/fast_classifier/offload_at_pkts)
About my values: I actually rrmod shortcut-fe-cm, after 4 hours the values look like this:
[ root: ~ ]# cat /sys/fast_classifier/debug_info
size=4 offload=0 offload_no_match=0 offloaded=0 done=0 offloaded_fail=11 done_fail=9
o=1, p=17 [xx::xx:xx:xx:xx]:192.168.xx.xx:xxxxx xxx.xxx.xxx.xxx:xxx:[00:00:00:00:00:00] m=00000000 h=27029788
Please note that: only 1 laptop is active that uses VPN via UPD (!). During the evening I'll try it out with the other one (disabling VPN on it) and take a look at these values.
lsmod output looks like this after removing shortcut-fe-cm:
[ root: ~ ]# lsmod | grep fast
