This workaround only applied to kernels earlier than 2.6.37, but OVS
only supports 3.10 and later.
As the original author of this code, I won't miss it.

The coding style guidelines include the following:
- Pick a unique name prefix (ending with an underscore) for each
module, and apply that prefix to all of that module's externally
visible names. Names of macro parameters, struct and union members,
and parameters in function prototypes are not considered externally
visible for this purpose.
This patch adds the new prefix to the externally visible names. This
makes it a bit more obvious what code is coming from common command
line handling code.

This allows other libraries to use util.h that has already
defined NOT_REACHED.

This appears to be required when building using the Android NDK r6b
(Android API level 13).

Some Linux network drivers support a feature called "VLAN acceleration",
associated with a data structure called a "vlan_group". A vlan_group is,
abstractly, a dictionary that maps from a VLAN ID (in the range 0...4095)
to a VLAN device, that is, a Linux network device associated with a
particular VLAN, e.g. "eth0.9" for VLAN 9 on eth0.
Some drivers that support VLAN acceleration have bugs that fall roughly
into the following categories:
* Some NICs strip VLAN tags on receive if no vlan_group is registered,
so that the tag is completely lost.
* Some drivers size their receive buffers based on whether a vlan_group
is enabled, meaning that a maximum size packet with a VLAN tag will
not fit if a vlan_group is not configured.
* On transmit some drivers expect that VLAN acceleration will be used
if it is available (which can only be done if a vlan_group is
configured). In these cases, the driver may fail to parse the packet
and correctly setup checksum offloading and/or TSO.
The correct long term solution is to fix these driver bugs. To cope until
then, we have prepared a patch to the Linux kernel network stack that works
around these problems. This commit adds support for the workaround
implemented by that patch.
