Prevent ixgbe from putting the adapter into D3 during shutdown except when
we're going to power off the system, since doing that may generally cause
problems with kexec to happen (such problems were observed for igb and

and use the appropriate PCI PM callbacks in both of them.

Don't do the num_tx_queues based masking on calculating tx queue
index.

 1) num_tx_queues is not always power-of-2, because it also depends on
    the online cpu numbers. So the masking could be a performance bug
    on a 6 cpu system.
 2) queue_mapping will be limited by real_num_tx_queues=num_tx_queues
    in the generic netdev function set_cur_queue_map(). So the bound
    limiting here is not necessary.

falcon_sim_phy_event() used EFX_OWORD_FIELD, which operates on
bitfields in 128-bit values, on an event, which is a 64-bit value.
This should be harmless - these macros always use little-endian
ordering, so it would read and write back the following 8 bytes
unchanged - but it is obviously wrong.

The BUG_ON(skge->tx_ring.to_use != skge->tx_ring.to_clean) in skge_up()
was sometimes observed when setting MTU.

skge_down() disables the TX queue, but then reenables it by mistake via
skge_tx_clean().
Fix it by moving the waking of the queue from skge_tx_clean() to the
other caller. And to make sure start_xmit is not in progress on another
CPU, skge_down() should call netif_tx_disable().

The bug was reported to me by Jiri Jilek whose Debian system sometimes
failed to boot. He tested the patch and the bug did not happen anymore.

When I made the tun driver use non-linear packets as the preferred
option, it broke non-GSO users because they would end up allocating
a completely non-linear packet, which triggers a crash when we call
eth_type_trans.

This patch reverts non-GSO users to using linear packets and adds
a check to ensure that GSO users can't cause crashes in the same
way.

Hi:

gro: Normalise skb before bypassing GRO on netpoll VLAN path

When we detect netpoll RX on the GRO VLAN path we bail out and
call the normal VLAN receive handler.  However, the packet needs
to be normalised by calling eth_type_trans since that's what the
normal path expects (normally the GRO path does the fixup).

This patch adds the necessary call to vlan_gro_frags.
