Using strlcpy() at least avoids overflowing the destination buffer

though, which probably can't be solved here.

Some SoCs have per cpu interrupts for Ethernet events, the driver uses
a per CPU napi structure for this case. Some SoCs such as armada 3700
have a single interrupt for Ethernet events, the driver uses a global

The main motive of this patch is to lay down driver's
tc offload infrastructure in place.
With these changes tc can offload various supported flow
profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop
action. Dropped flows statistic is a global counter for
all the offloaded flows for drop action and is populated
in ethtool statistics as common "gft_filter_drop".
Examples -
tc qdisc add dev p4p1 ingress
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto tcp dst_ip 192.168.40.200 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
