be stripped.  Since the application did not request to enable VLAN
stripping it is not expecting these packets so they are not processed as
VLAN packets.

Regardless of the Virtual Box issue, the driver should be advertising

In the MCDI definitions, the unknown multicast and unicast flags
have the values 0x40000000 and 0x80000000 respectively, and so using
the same values for simplicity requires 32 bits in the filter

net/fm10k/base: improve VF multi-bit VLAN update requests

The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refactor broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set. In addition, a multi-bit vlan
update does not have a concept for "VLAN 0" as the single bit update
does.

A previous revision of this patch resolved the issue by simply removing
the upper 16 bit check and the iov_select_vid checks. However, this would
remove the checks for default VID and for ensuring no other VLANs can be
enabled except pf_vid when it has been set. To resolve that issue, this
revision uses the iov_select_vid when we have a single-bit update, and
denies any multi-bit update when the VLAN was administratively set by
the PF. This should be ok since the PF properly updates VLAN_TABLE when
it assigns the PF vid. This ensures that requests to add or "remove" the
PF vid work as expected, but a rogue VF could not use the multi-bit
update as a loophole to attempt receiving traffic on other VLANs.

net/vmxnet3: introduce generalized cmd interface

Shared memory is used to exchange information between the vmxnet3 driver
and the emulation. In order to request emulation to perform a task, the
driver first populates specific fields in this shared memory and then
issues corresponding command by writing to the command register(CMD). The
layout of the shared memory was defined by vmxnet3 version 1 and cannot
be extended for every new command without breaking backward compatibility.

To address this problem, in vmxnet3 version 3, the emulation repurposed
a reserved field in the shared memory to represent command information
instead. For new commands, the driver first populates the command
information field in the shared memory and then issues the command. The
emulation interprets the data written to the command information
