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
