Only let the rx parser be enabled if it is necessary (if VLAN extraction,
IP or TCP checksumming or the rx queue filer are enabled). Otherwise
disable it.
The new routine gfar_check_rx_parser_mode should be run after every
change on this features and will enable/disable the parser as necessary.

Ugh this was already applied on net-2.6. Dave please sync and ignore
this. Sorry.
Thanks.

Since vlan_group_get_device and vlan_group is not going to be accessible

Just remove this line - nes_fix_features() is controlling the flag anyway.

This is unconditionally true, right? NETIF_F_HW_VLAN_RX never gets
toggled here. In any case, I think we should be able to handle vlan
tagged packets even if stripping isn't enabled.
The Intel guys have expressed some concerns in the past about the MTU
in relation to the igb driver (the PF version) with vlan tags. I'm
not quite sure what about this NIC is different from others in the
handling of MTU and vlans but here's one such thread:

You are correct. This should be checked rather if any bit of
adapter->active_vlans is set. I'll repost soon.

I'm pretty sure you intended to put a curly brace after the if statement here.
Other than that it seems fine.

Right, missed that. Thanks.
Rsposting also with removing igbvf_set_rlpml call from
igbvf_restore_vlan since it is called from igbvf_configure_rx

There are similar issues here as with the VF driver. I think you're
also confusing vlan acceleration with vlan filtering. If no vlan
filters are in use but the card is in promiscuous mode, the buffer
will be undersized and we lose tagged packets.

This should be controlled by ethtool, not by whether vlan filters are
enabled. Essentially, with this, you are recreating the logic of the
old vlan model in the new one.

I'm certainly not confusing vlan accel and filtering. Here is the
intension is the behaviour remains intact as well. I believe it's true.

I believe the underlying issue for all three of these threads is the
same, so I'll just respond to them all here.
I agree that this doesn't change the behavior of the driver but I
don't think that should be the goal. When I originally designed this
new vlan model my intention was to eliminate a whole class of driver
bugs that I was repeatedly hitting in various forms. In the example
above, if you run tcpdump on this device without configuring a vlan
group on it then you will see that MTU sized packets are missing
because the receive buffer was undersized.
The common theme for these problems is that they all occur in
situations where vlans are not configured on the device and the driver
does something different as a result of this. The solution was to
prevent drivers from changing their behavior in such situations by
completely removing the concept of a vlan group from them and letting
the networking core tell them when to make the changes instead of
doing it implicitly. That's why I don't see the fact that this change
essentially emulates the knowledge of configuring a group to be a
plus. By the way, plenty of your other patches change the behavior of
the drivers - on any of the NICs that always enable stripping, try
running tcpdump on the interface without configuring a vlan group.
Before the change you will see that tags have disappeared and
afterwards the tags are intact. So I think that changing the behavior
of drivers in this regard is a positive thing.
As an aside, thank you for taking the time to work on all of these
drivers. The only reason why I'm complaining about these few drivers
is because I'd like to close the door on this class of problems, which
is finally in reach thanks to your work.

Okay now it's clear to me. I tried to stay with the code as much similar
as unpatched. But I see your arguments. I will review and repost
patches which are enabling/disabling vlan accel on add_vid/kill_vid and
convert it to set_features.
Thanks. Jesse.

Now when all devices are cleaned up, bond can be cleaned up as well
- remove bond->vlgrp
- remove bond_vlan_rx_register
