Since implementing VLAN filtering in commit 05cc5a39ddb74
("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while
the interface is down:
# ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10
RTNETLINK answers: Bad address
and in dmesg (with bnx2x.debug=0x20):
bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN
configuration the interface is down
Other drivers have no problem with this.
Fix this peculiar behavior in the following way:
- Accept requests to add/kill VID regardless of the device state.
Maintain the requested list of VIDs in the bp->vlan_reg list.
- If the device is up, try to configure the VID list into the hardware.
If we run out of VLAN credits or encounter a failure configuring an
entry, fall back to accepting all VLANs.
If we successfully configure all entries from the list, turn the
fallback off.
- Use the same code for reconfiguring VLANs during NIC load.
Have to change the signed-off-by line to avoid spam to original people.

The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it
to 4.4.50-rt62.
The command to achieve it is:
a) Clone a git repo from
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git
b) Get the diff between this two changesets:
git diff 640eca2901f3435e616157b11379d3223a44b391
705619beeea1b0b48219a683fd1a901a86fdaf5e
where the two commits are:
[yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only
640eca2901f3435e616157b11379d3223a44b391

[yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only

705619beeea1 Linux 4.4.50-rt62
localversion-rt
c) One patch has been backported thus revert the patch before applying.

Use HWRM_FW_RESET command to request a self-reset of the embedded
processor(s) after successfully applying a firmware update. For boot
processor, the self-reset is currently deferred until the next PCIe reset.

are taken from kernel.org, and rt patch from the rt wiki download page.
During the rebasing, the following patch collided:
Force tick interrupt and get rid of softirq magic(I70131fb85).
Collisions have been removed because its logic was found on the
source already.

Currently the vfio msi interrupt is kept as IRQ thread, this is not good
for NFV scenerio because in NFV scenerio, we want to inject the interrupt
to the guest asap. A threaded IRQ introduces schedule latency.
However, this change is like a quick and dirty and may bring
potential deadlock, because the spinlock_irqsave() from eventfd_signal()
is preemptible in RT kernel, which should not be held on IRQ context. But
changing it to be raw_spinlock is bad because it will increase the latency
a lot if the eventfd is accessed by user space.
The deadlock should be ok since for vfio MSI handler is purely kernel story
and the lock is a per-eventfd lock and seems no one else is using it for the
vfio msi scenario.

Import the rt linux 4.1.3-rt3 as OPNFV kvm base.
It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and
the base is:
commit 0917f823c59692d751951bf5ea699a2d1e2f26a2
Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: Sat Jul 25 12:13:34 2015 +0200
Prepare v4.1.3-rt3
Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.
