[PATCH intel-net 0/5] i40e: ice: ixgbe: ixgbevf: igb: add correct exception tracing for XDP

[PATCH intel-net 0/5] i40e: ice: ixgbe: ixgbevf: igb: add correct exception tracing for XDP

[Magnus Karlsson]

Add missing exception tracing to XDP when a number of different errors
can occur. The support was only partial. Several errors where not
logged which would confuse the user quite a lot not knowing where and
why the packets disappeared.

This patch set fixes this for all Intel drivers with XDP support.

Thanks: Magnus

[PATCH intel-net 4/5] igb add correct exception tracing for XDP

[Magnus Karlsson]

From: Magnus Karlsson <magnus.karlsson@intel.com>

Add missing exception tracing to XDP when a number of different
errors can occur. The support was only partial. Several errors
where not logged which would confuse the user quite a lot not
knowing where and why the packets disappeared.

This doesn't apply anymore with the 5.13 patches. It looks like your
"optimize for XDP_REDIRECT in xsk path" patches are conflicting with
some of these. Did you want to rework them?

Thanks for working on this Magnus, highly appreciated.  This should
help end-users troubleshoot these kind of 'exception' packet drops.

We have people that will look at updating the sample/bpf/ programs
(that does XDP redirect) to report on these exception errors/drops.

> Add missing exception tracing to XDP when a number of different errors can

> would confuse the user quite a lot not knowing where and why the packets
> disappeared.
