Bruce Allan 5f4a780ddd e1000e: hitting BUG_ON() from napi_enable
Based on a patch from Mike McElroy created against the out-of-tree e1000e
driver:

Hitting the BUG_ON in napi_enable(). Code inspection shows that this can
only be triggered by calling napi_enable() twice without an intervening
napi_disable().

I saw the following sequence of events in the stack trace:

1) We simulated a cable pull using an Extreme switch.
2) e1000_tx_timeout() was entered.
3) e1000_reset_task() was called. Saw the message from e_err() in the
console log.
4) e1000_reinit_locked was called. This function calls e1000_down() and
e1000_up(). These functions call napi_disable() and napi_enable()
respectively.
5) Then on another thread, a monitor task saw carrier was down and executed
'ip set link down' and 'ip set link up' commands.
6) Saw the '_E1000_RESETTING'warning fron the e1000_close function.
7) Either the e1000_open() executed between the e1000_down() and e1000_up()
calls in step 4 or the e1000_open() call executed after the e1000_up()
call.  In either case, napi_enable() is called twice which triggers the
BUG_ON.

Jeff Kirsher 09357b0025 e1000e: Avoid wrong check on TX hang
Based on the original patch submitted my Michael Wang
<wangyun@linux.vnet.ibm.com>.
Descriptors may not be write-back while checking TX hang with flag
FLAG2_DMA_BURST on.
So when we detect hang, we just flush the descriptor and detect
again for once.

-v2 change 1 to true and 0 to false and remove extra ()

Eric Dumazet 1f2149c1df net: remove netdev_alloc_page and use __GFP_COLD
Given we dont use anymore the struct net_device *dev argument, and this
interface brings litle benefit, remove netdev_{alloc|free}_page(), to
debloat include/linux/skbuff.h a bit.

(Some drivers used a mix of these interfaces and alloc_pages())

When allocating a page given to device for DMA transfer (device to
memory), it makes sense to use a cold one (__GFP_COLD)

John Fastabend 8599e251b3 ixgbe: DCB, return max for IEEE traffic classes
Returning the max traffic classes on get requests simplifies
user space configurations because applications will know
explicitly how many traffic classes can be used.

Typical switch implementations use 2 or 3 traffic classes
so this not seen often today. And user space can learn
the number of traffic classes by return codes but this
allows user space to configure ixgbe correctly at the
start.

Carolyn Wyborny 65189d284b igb: Fix for Alt MAC Address feature on 82580 and later devices
In 82580 and later devices, the alternate MAC address feature is
completely handled by the option ROM and software does not handle
it anymore.  This patch changes the check_alt_mac_addr function to
exit immediately if device is 82580 or later.

To ease skb->truesize sanitization, its better to be able to localize

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

Greg Rose 0224d66306 igb: Check if subordinate VFs are assigned to virtual machines
Kvm and the Xen pci-back driver will set a flag in the virtual function
pci device dev_flags when the VF is assigned to a guest VM.  Before
destroying subordinate VFs check to see if the flag is set and if so
skip the call to pci_disable_sriov() to avoid system crashes.

Copy the maintainer for the Xen pci-back driver.  Also CC'ing
maintainers of all drivers found to call pci_disable_sriov().

Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM.
Removing this needs deeper surgery.

Things noticed:
 - HW VLAN acceleration probably can be toggled, but it's left as is
 - the resets on RX csum offload change can probably be avoided
 - there is A LOT of copy-and-pasted code here
