Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Various different arm32 JIT improvements in order to optimize code emission
and make the JIT code itself more robust, from Russell.
2) Support simultaneous driver and offloaded XDP in

Since commit 9516823051ce ("ipaddress: Improve print_linkinfo()") we
return -1 instead of 0 when ip-address(8) label does not match network
device name as we did before change. This causes regression when trying
to output ip address matching label:
# ip addr add 192.168.192.1/24 dev lo label

This patch fixes patch add handling to take care tail and headroom for
single 6lowpan frames. We need to be sure we have a skb with the right
head and tailroom for single frames. This patch do it by using
skb_copy_expand() if head and tailroom is not enough allocated by upper
layer.

An IP packet received on a netdev with a macvlan upper whose MAC matches
the packet's destination MAC will be re-injected to the Rx path as if it
was received by the macvlan, and perform an L3 lookup.
Reflect this functionality to the ASIC by programming FDB entries that
will direct MACs of macvla
In order to allow more unicast MAC addresses (e.g., VRRP virtual MAC) to
be directed to the router we need to enable macvlan uppers on top of
mlxsw netdevs.
Allow macvlan upper devices on top of mlxsw netdevs and sanitize
configurations that can't work. For example, a macvlan can't be enslaved

Virtual Router Redundancy Protocol packets are used to communicate the
state of the Master router associated with the virtual router ID (VRID).
These are link-local multicast packets sent with IP protocol 112 that
are trapped in the router block in the ASIC.
Add a trap for these packets and mark
Hosts using a VRRP router send their packets with a destination MAC of
the VRRP router which is of the following form [1]:
IPv4 - 00-00-5E-00-01-{VRID}
IPv6 - 00-00-5E-00-02-{VRID}
Where VRID is the ID of the virtual router. Such packets are directed to
the router block in the ASIC by an FDB entr
When a router that is acting as the default gateway of a host stops
functioning, the host will encounter packet loss until the router starts
functioning again.
To increase the reliability of the default gateway without performing
reconfiguration on the host, a host can use a Virtual Router Redunda

The new action inheritdsfield copies the field DS of
IPv4 and IPv6 packets into skb->priority. This enables
later classification of packets based on the DS field.
