* device/if_hdr.h (struct ifnet): Added new members `if_snd_port_list'
and `if_snd_port_list_lock'.
* device/net_io.c: Reworked to improve BPF support. Filters can be
applied to ingress packets, egress packets, or both.
* device/subrs.c: Initialize the `if_snd_port_list' and
`if_snd_port_list_lock'.
* include/device/bpf.h [0]: Enable unconditionally.
Include <sys/types.h>.
(BPF_IN, BPF_OUT): New macros.
* include/device/net_status.h (NETF_TYPE_MASK, NETF_IN, NETF_OUT): New
macros.
(struct net_rcv_msg): New member `sent'.
* linux/dev/glue/net.c: Mark ingress packets as received and inject
egress packets into the packet filters.
