Introduce a new bpf map type 'BPF_MAP_TYPE_PERF_EVENT_ARRAY'.
This map only stores the pointer to struct perf_event. The
user space event FDs from perf_event_open() syscall are converted
to the pointer to struct perf_event and stored in map.

Previously we only checked if the transmission queue is not full in the
middle of the xmit function. This lead to complex logic due to the fact
that sometimes we need to reallocate the headroom for our Tx header.
Allow the switch driver to know if the

This resolves compile errors on um-allyesconfig.
Note that there are many other drivers which have the same issue.

Hi Vivien
Thanks for splitting up the big patch. This it is much easier to
review now.
Is this patch git bisectable?
In terms of compilation, yes.
Clearly after this patch, but before all the other patches are in, we
will not be programming the

Store the length of the skb before transmitting it and use it for stats
instead of skb-len, since skb might have been freed already.
This issue was discovered using the Kernel Address sanitizer (KASan).

When removing a port's netdevice we should also free the memory
allocated by alloc_etherdev(). Do this by calling free_netdev() at the
end of the teardown sequence.

Do not use the length of the transmitted skb (which was freed), but
that of the response skb.

Like the ipv4 patch with a similar title, this adds a sysctl to allow
the user to change routing behavior based on whether or not the
interface associated with the nexthop was an up or down link. The
default setting preserves the current behavior, but anyone that enables
it will notice that
Add support to track current link status of ipv6 nexthops to match
recent changes that added support for ipv4 nexthops. There was not a
field already available that could track these and no space available in
the existing rt6i_flags field, so this patch adds rt6i_nhflags to struct
rt6_info.
