In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).

Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

We currently allow changing the mq flag (IFF_MULTI_QUEUE) for a persistent
device. This will result a mismatch between the number the queues in netdev and
tuntap. This is because we only allocate a 1q netdevice when IFF_MULTI_QUEUE was
not specified, so when we set the IFF_MULTI_QUEUE and try to attach more queues
later, netif_set_real_num_tx_queues() may fail which result a single queue
netdevice with multiple sockets attached.

Solve this by disallowing changing the mq flag for persistent device.

Bug was introduced by commit edfb6a14
(tuntap: reduce memory using of queues).

In function be_get_nic_desc(), it will go through the descriptor array
returned from f/w. By comparing the desc_type field, it determines whether
there is a nic descriptor in the array or not. In the case of no nic
descriptor, this function should return NULL.

The code may return an invalide descriptor, when there is no nic descriptor
in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
even there is no nic descriptor, it will still return the lase descriptor
since the i doesn't equal to MAX_RESOURCE_DESC.

This patch fix this issue by returning the descriptor when find it and return
NULL for other cases.

After resetting the device, the driver waits for a signature to be
updated to know that firmware has completed initialization. However, the
call to tg3_poll_fw() is being done too late and we're writing to the
GRC_MODE register before it has completely initialized, causing
contention with firmware.  This logic has existed since day one but is
causing PCIE link to go down randomly at startup on one platform once
every few hundred reboots.

Move the tg3_poll_fw() up to before we write to the GRC_MODE register
after reset.
