John Fastabend 45a5f720fe ixgbe: DCB, X540 devices do not respond to pause frames
DCB enabled X540 devices are not responding to pause frames
due to a missing register set that was added for these
devices that did not exist in other devices.

John Fastabend e09ad236fc ixgbe: DCB, misallocated packet buffer size with X540 device
The X540 device has a smaller packet buffer but the DCB configuration
never took this into account. Under stress this can result in the DMA
engine hanging and TX Unit hang occurring to reset the device. This
patch reworks the packet buffer allocation routine used for DCB on
82599 and X540 devices to account for RX packet buffer sizes.

This fixes the immediate hang. We should consolidate the various
hardware specific routines for configuring features into a single
routine. This will make it much harder to miss feature cases like
this.

Bruce Allan 78cd29d5a9 e1000e: If ASPM L0s needs to be disabled, do it prior to enabling device
Based on a patch from Naga Chumbalkar <nagananda.chumbalkar@hp.com>:

If ASPM L0s needs to be disabled due to HW errata, do it prior to
"enabling" the device. This way if the kernel ever defaults its
aspm_policy to POLICY_POWERSAVE, then the e1000e driver will get a
chance to disable ASPM on the misbehaving device *prior* to calling
pci_enable_device_mem(). This will be useful in situations
where the BIOS indicates ASPM support on the server by clearing the
ACPI FADT "ASPM Controls" bit.

Note:
The kernel (2.6.38) currently uses the BIOS "default" as its aspm_policy.
However, Linux distros can diverge from that and set the default to
"powersave".

v2: o cleanup namespace pollution of e1000e_disable_aspm(),
    o fix type and initialization of the new aspm_disable_flag in a few
      functions, and
    o redefine FLAG2_DISABLE_ASPM_L0S to the first unused bit in
      adapter->flags2.

enabled, skb is untagged by NIC, vlan_tci is set and the skb gets into
vlan code in __netif_receive_skb - vlan_hwaccel_do_receive.

For non-rx-vlan-hw-accel however, tagged skb goes thru whole
__netif_receive_skb, it's untagged in ptype_base hander and reinjected

This incosistency is fixed by this patch. Vlan untagging happens early in
__netif_receive_skb so the rest of code (ptype_all handlers, rx_handlers)
see the skb like it was untagged by hw.

Jon Mason 9f9b164581 vxge: spin-lock issue
In vxge_hw_vpath_close, __vxge_hw_vp_terminate memsets the vpath which
clobbers the spin lock state, then the driver attempts to acquire the
spin lock.  Resolve this by not zeroing the lock part of vpath struct,
clean-up vpath locking in init, close, and fix locking hole in fw_api
call.

Jon Mason cd883a791b vxge: always enable hardware time stamp
Hardware time stamp calculation can only be enabled by the privileged
function. Enable it always by default and simply use the ethtool
interface to set a flag to indicate whether or not the respective
function driver should indicate the timestamp along with the received
packet.

Also, make certain fields in vxge_hw_device_config bit-fields to reduce
the size of the struct.
