Because the order of the parameters passes to 'hlist_add_behind()' was
inverted, the 'parent' node was added "behind" the 'input', as input
is not in the list, this causes the 'input' node to be lost.

Hi,
This series enables some ethtool and tc-flower filters to be offloaded
to igb-based network controllers. This is useful when the system

The first two commits are bug fixes.
The basis of this series is to export the int

RDS applications use predominantly request-response, transacation

This adds the capability of configuring the queue steering of arriving

In practical terms this adds support for the following use cases,

This allows filters added by tc-flower and specifying MAC addresses,

This reuses most of the infrastructure used by ethtool, ethtool can be

Except for tuntap, all other drivers' XDP was implemented at NAPI
poll() routine in a bh. This guarantees all XDP operation were done at
the same CPU which is required by e.g BFP_MAP_TYPE_PERCPU_ARRAY. But
for tuntap, we do it in process context and we try to protect XDP
processing by RCU reader lo
We don't flush batched XDP packets through xdp_do_flush_map(), this
will cause packets stall at TX queue. Consider we don't do XDP on NAPI
poll(), the only possible fix is to call xdp_do_flush_map()
immediately after xdp_do_redirect().
Note, this in fact won't try to batch packets through devmap,
This reverts commit 762c330d670e3d4b795cf7a8d761866fdd1eef49. The
reason is we try to batch packets for devmap which causes calling
xdp_do_flush() in the process context. Simply disabling preemption
may not work since process may move among processors which lead
xdp_do_flush() to miss some flushes
