where interface renaming is not supported (NetBSD), remember both of
our netdev name and the correspoinding kernel name separately.
the latter is necessary to talk with kernel using interface names.
eg. ifioctls, bpf
XXX there should be a proper way to query kernel name.
Ben Pfaff suggested ovs-appctl but this patch doesn't implement it. (yet)

The distinction between struct netdev_dev and struct netdev has always
been confusing. Now that previous commits have eliminated all interesting
state from struct netdev, this commit deletes it and renames struct
netdev_dev to take its place. Now the situation makes much more sense and
I won't have to continue making embarrassed explanations in the future.
Good riddance.

Separating packet capture from "struct netdev" means that there is no
remaining per-"struct netdev" state, which will allow us to get rid of
"struct netdev_dev" (by renaming it "struct netdev").

This file presumably started out life as a copy of netdev-linux.c, and
some indentation was not updated after s/linux/bsd/.

This gets rid of the only per-instance data in "struct netdev", which
will make it possible to merge "struct netdev_dev" into "struct netdev" in
a later commit.

This is a trivial port to netdev-bsd of Justin Pettit's netdev-linux
commit 33d82a56d (netdev-linux: Use underlying tap device on
netdev_linux_listen().), which had the commit message:
Commit acf608 (ofproto-dpif: Use a single underlying datapath across
multiple bridges.) broke connectivity to userspace datapath devices. The
code assumed the first caller to open a tap device with
netdev_linux_open() wanted to write to it. This commit moves that logic
to when netdev_linux_listen() is called.
This fixes the userspace datapath on FreeBSD.

FreeBSD's system compiler is a somewhat old version of GCC that produced

This patch adds new netdev classes that implement
"system" and "tap" devices on FreeBSD using the
libpcap library. This enables the use of the
"netdev" datapath_type of Open vSwitch on FreeBSD.
