If it is not zero, it is an error. !0 is always !0, big or little

Intention of this post is to get some early review and wider testing.
This series adds CPTS IRQ support, which allows to fix TX timestamping issue
and add support for HW_TS_PUSH events.
The idea of using CPTS IRQ for proper support of HW_TS_PUSH events
was originally discussed in [1].
Further TX
There could be significant delay in CPTS work schedule under high system
load and on -RT which could cause CPTS misbehavior due to internal counter
overflow. Usage of own highpri ordered workqueue allows to avoid such kind
of issues and makes it possible to tune priority of CPTS workqueue thread
on
There are two reasons for this change:
1) enabling of HW_TS_PUSH events as suggested by Richard Cochran and
discussed in [1]
2) fixing an TX timestamping miss issue which happens with low speed
ethernet connections and was reproduced on am57xx and am335x boards.

Today, if users try to access a ctx field through a narrower load, e.g.,
__be16 prot = __sk_buff->protocol, verifier will fail.
This set contains the verifier change to permit such loads for
certain ctx fields as well as the new test cases in selftests/bpf.
Yonghong Song (2):
bpf: permits narrow
Currently, verifier will reject a program if it contains an
narrower load from the bpf context structure. For example,
__u8 h = __sk_buff->hash, or
__u16 p = __sk_buff->protocol
__u32 sample_period = bpf_perf_event_data->sample_period
which are narrower loads of 4-byte or 8-
Add test cases in test_verifier and test_progs.
Negative tests are added in test_verifier as well.
The test in test_progs will compare the value of narrower ctx field
load result vs. the masked value of normal full-field load result,
and will fail if they are not the same.

Instead of doing a linear search through the insn_table for each

Expose prog_id through IFLA_XDP_PROG_ID. This patch
makes modification to generic_xdp. The later patches will
modify other xdp-supported drivers.
prog_id is added to struct net_dev_xdp.
iproute2 patch will be followed. Here is how the 'ip link'
will look like:
> ip link show eth0

This is the first usage of the new bpf_prog ID. It is for
reporting the ID of a xdp_prog through netlink.
It rides on the existing IFLA_XDP. This patch adds IFLA_XDP_PROG_ID
for the bpf_prog ID reporting.
It starts with changing the generic_xdp first. After that,
the hardware driver is changed
Add support to virtio_net to report bpf_prog ID during XDP_QUERY_PROG.
