bpftool: support loading flow dissector
This commit adds support for loading/attaching/detaching flow
dissector program.
When `bpftool loadall` is called with a flow_dissector prog (i.e. when the
'type flow_dissector' argument is passed), we load and pin all programs.
User is responsible to construct the jump table for the tail calls.
The last argument of `bpftool attach` is made optional for this use
case.
Example:
bpftool prog load tools/testing/selftests/bpf/bpf_flow.o \
/sys/fs/bpf/flow type flow_dissector \
pinmaps /sys/fs/bpf/flow
bpftool map update pinned /sys/fs/bpf/flow/jmp_table \
key 0 0 0 0 \
value pinned /sys/fs/bpf/flow/IP
bpftool map update pinned /sys/fs/bpf/flow/jmp_table \
key 1 0 0 0 \
value pinned /sys/fs/bpf/flow/IPV6
bpftool map update pinned /sys/fs/bpf/flow/jmp_table \
key 2 0 0 0 \
value pinned /sys/fs/bpf/flow/IPV6OP
bpftool map update pinned /sys/fs/bpf/flow/jmp_table \
key 3 0 0 0 \
value pinned /sys/fs/bpf/flow/IPV6FR
bpftool map update pinned /sys/fs/bpf/flow/jmp_table \
key 4 0 0 0 \
value pinned /sys/fs/bpf/flow/MPLS
bpftool map update pinned /sys/fs/bpf/flow/jmp_table \
key 5 0 0 0 \
value pinned /sys/fs/bpf/flow/VLAN
bpftool prog attach pinned /sys/fs/bpf/flow/flow_dissector flow_dissector
Tested by using the above lines to load the prog in
the test_flow_dissector.sh selftest.
