Hi Björn and Magnus,
Here is a short update on the proposed changes to AF_XDP.
During implementation phase I figured out that 'end-of-page' in RX
descriptor's flags won't work, unfortunately. This is because the
kernel driver can't know if the frame will be last on the page when RX
descriptor is

Currently, AF_XDP only supports a fixed frame-size memory scheme where

Commit bf6fa2c893c5 ("bpf: implement bpf_get_current_cgroup_id()

The helper has a dependency on CONFIG_CGROUPS.
When CONFIG_CGROUPS is not defined, using the helper will result

This adds two new helper functions to trace_helpers that supports polling
multiple perf file descriptors for events. These are used to the XDP
perf_event_output example, which needs to work with one perf fd per CPU.

This adds an example program showing how to sample packets from XDP using
the perf event buffer. The example userspace program just prints the
ethernet header for every packet sampled.
The example sets up a perf file descriptor per CPU, allowing the XDP
program to pass BPF_F_CURRENT_CPU and work n

Updated the e1000.txt kernel documentation with the latest information.
Also convert the text file to reStructuredText (RST) format, since the

Similar to ixgbevf, the same possibility for race exists. Extend the RTNL
lock in ixgbe_reset_subtask() to protect the state bits; this is to make
