When a device is suspended, it doesn't need to be as responsive to

From: David Ahern
Add support to run Tx path program on xdp_frames by adding a hook to
bq_xmit_all before xdp_frames are passed to ndo_xdp_xmit for the device.
If an xdp_frame is dropped by the program, it is removed from the
xdp_frames array with subsequent entries moved up.

New section name hint, xdp_egress, is added to set expected attach
type at program load. Programs can use xdp_egress as the prefix in
the SEC statement to load the program with the BPF_XDP_EGRESS
attach type set.
egress_prog_id is added to xdp_link_info to report the program
id

xdp1 and xdp2 now accept -E flag to set XDP program in the egress
path.

This patch handles the plumbing for installing an XDP egress
program on a net_device by handling XDP_SETUP_PROG_EGRESS and
XDP_QUERY_PROG_EGRESS in generic_xdp_install handler. New static
key is added to signal when an egress program has been installed.
Update dev_xdp_uninstall
From: David Ahern
Add xdp_egress attach tests:
1. verify egress programs cannot access ingress entries in xdp context
2. verify ability to load, attach, and detach xdp egress to a device.

From: David Ahern
Add xdp_egress as a program type since it requires a new attach
type. This follows suit with other program type + attach type
combintations and leverages the SEC name in libbpf.

allow a user to specify 'xdp_egress
From: David Ahern
Add new bpf_attach_type, BPF_XDP_EGRESS, for BPF programs attached
at the XDP layer, but the egress path.
Since egress path will not have ingress_ifindex and rx_queue_index
set, update xdp_is_valid_access to block access to these entries in
the xdp context when a program is att
From: David Ahern
Add new netdev commands, XDP_SETUP_PROG_EGRESS and
XDP_QUERY_PROG_EGRESS, to query and setup egress programs.

via XDP_FLAGS_EGRESS_MODE in the flags. If egress bool is set, then use
XDP_SETUP_PROG_EGRESS in d
From: David Ahern
Running programs in the egress path, on skbs or xdp_frames, does not
require driver specific resources like Rx path. Accordingly, the
programs can be run in core code, so add xdp_egress_prog to net_device
to hold a reference to an attached program.
For UAPI, add XDP_FLAGS_EGRES
From: David Ahern
Move the guts of convert_to_xdp_frame to a new helper, update_xdp_frame
so it can be reused in a later patch.

include/net/xdp.h | 30 ++
From: David Ahern
This series adds support for XDP in the egress path by introducing
a new XDP attachment type, BPF_XDP_EGRESS, and adding a UAPI to
if_link.h for attaching the program to a netdevice and reporting
the program. This allows bpf programs to be run on redirected xdp
frames with the c
