I did notice a little difference between TC and Kernel, below is the
kernel and it has flags as (df) where tc does not have this. Is this
a bug in tc?
Forgot to address this comment. I found this comment:
/* XXX: This is wrong! We're ignoring DF and CSUM flags
configuration
* requested by the user. However, TC for now has no way to pass
* these flags in a flower key and their masks are set by default,
* meaning tunnel offloading will not work at all if not cleared.
* Keeping incorrect behavior for now. */
tnl_mask->flags &= ~(FLOW_TNL_F_DONT_FRAGMENT | FLOW_TNL_F_CSUM);
Maybe it's a known issue.
