Hello,
I am getting this trace from my driver which I ported from 2.6.32-431 to
3.10.0-123 kernel.
The driver works just fine on 2.6.32-431 kernel but not on 3.10.0-123 after
porting.
Ping works fine on 3.10.0-123 but I get this trace when I run ssh or tcp
traffic.
Please find the attached wireshark traces of both machines in between ssh
was tried.
Please help.
