commit 01f7feeaf4528bec83798316b3c811701bac5d3e upstream.

Two bits control TX power on BBP_R1 register. Correct the mask,
otherwise we clear additional bit on BBP_R1 register, what can have
unknown, possible negative effect.

team: avoid race condition in scheduling delayed work

2014-10-15T10:05:30+00:00

[ Upstream commit 47549650abd13d873fd2e5fc218db19e21031074 ]

When team_notify_peers and team_mcast_rejoin are called, they both reset
their respective .count_pending atomic variable. Then when the actual
worker function is executed, the variable is atomically decremented.
This pattern introduces a potential race condition where the
.count_pending rolls over and the worker function keeps rescheduling
until .count_pending decrements to zero again:

THREAD 1                           THREAD 2

========                           ========
team_notify_peers(teamX)
  atomic_set count_pending = 1
  schedule_delayed_work
                                   team_notify_peers(teamX)
                                   atomic_set count_pending = 1
team_notify_peers_work
  atomic_dec_and_test
    count_pending = 0
  (return)
                                   schedule_delayed_work
                                   team_notify_peers_work
                                   atomic_dec_and_test
                                     count_pending = -1
                                   schedule_delayed_work
                                   (repeat until count_pending = 0)

Instead of assigning a new value to .count_pending, use atomic_add to
tack-on the additional desired worker function invocations.

net/mlx4: Correctly configure single ported VFs from the host

2014-10-15T10:05:29+00:00

[ Upstream commit a91c772fa0275163508e1078ff6d474d423244fb ]

Single port VFs are seen PCI wise on both ports of the PF (we don't have
single port PFs with ConnectX). With this in mind, it's possible for
virtualization tools to try and configure a single ported VF through
the "wrong" PF port.

To handle that, we use the PF driver mapping of single port VFs to NIC
ports and adjust the port value before calling into the low level
code that does the actual VF configuration

net/mlx4_core: Allow not to specify probe_vf in SRIOV IB mode

2014-10-15T10:05:29+00:00

[ Upstream commit effa4bc4e75a265105f4ccb55857057e5ad231ed ]

When the HCA is configured in SRIOV IB mode (that is, at least one of
the ports is IB) and the probe_vf module param isn't specified,
mlx4_init_one() failed because of the following condition:

if (ib_ports && (num_vfs_argc > 1 || probe_vfs_argc > 1)) {
	 .....
}

The root cause for that is a mistake in the initialization of num_vfs_argc
and probe_vfs_argc. When num_vfs / probe_vf aren't given, their argument
count counterpart should be 0, fix that.
