Subject: [PATCH iproute2 0/3] ip-link: XDP flags and offload mode

Hi!

This series adds support for specifying DRV_MODE and new HW_MODE
flags when binding an XDP program to the driver.  It also teaches
ip link about "xdpoffload" attachment mode.

Examples:
# ip link set dev p4p1 xdpoffload obj prog.o sec '.text'
# ip link show dev p4p1
60: p4p1: <BROADCAST,MULTICAST> mtu 1500 xdpoffload/id:2 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:15:4d:12:27:6b brd ff:ff:ff:ff:ff:ff
# ip link set dev p4p1 xdpoffload off

Note: this is based on top of Martin's "bpf: Add support for 
IFLA_XDP_PROG_ID".

Jakub Kicinski (3):
  bpf: print xdp offloaded mode
  bpf: add xdpdrv for requesting XDP driver mode
  bpf: allow requesting XDP HW offload
