Casey Leedom 53c7886c18 cxgb4vf: don't implement trivial (and incorrect) ndo_select_queue()
Don't implement (struct net_device_ops *)->ndo_select_queue() with simple
call to skb_tx_hash().  This leads to non-persistent TX queue selection in
the Linux dev_pick_tx() routine for TCP connections.

Kulikov Vasiliy 7a0c2029d6 cxgb4vf: do not use PCI resources before pci_enable_device()
IRQ and resource[] may not have correct values until
after PCI hotplug setup occurs at pci_enable_device() time.

The semantic match that finds this problem is as follows:

// <smpl>
@@
identifier x;
identifier request ~= "pci_request.*|pci_resource.*";
@@

(
* x->irq
|
* x->resource
|
* request(x, ...)
)
 ...
*pci_enable_device(x)
// </smpl>

Casey Leedom 7f9dd2fa4a cxgb4vf: fix TX Queue restart
Fix up TX Queue Host Flow Control to cause an Egress Queue Status Update to
be generated when we run out of TX Queue Descriptors.  This will, in turn,
allow us to restart a stopped TX Queue.
