This patch removes some dead code from the cleanup path for ixgbe.
Setting and clearing the flag doesn't do anything since all we are
doing is setting the flag, scheduling NAPI, clearing the flag and
then letting netpoll do the polling cleanup. As such it doesn't
make much sense to have it there.
This patch also removes one minor white-space error.

overlapped with an endainness fix for VHOST 1.0 in 'net'.
In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter

This change makes it so that dma_rmb is used when reading the Rx
descriptor. The advantage of dma_rmb is that it allows for a much
lower cost barrier on x86, powerpc, arm, and arm64 architectures than a
traditional memory barrier when dealing with reads that only have to
synchronize to coherent memory.
In addition I have updated the code so that it just checks to see if any
bits have been set instead of just the DD bit since the DD bit will always
be set as a part of a descriptor write-back so we just need to check for a
non-zero value being present at that memory location rather than just
checking for any specific bit. This allows the code itself to appear much
cleaner and allows the compiler more room to optimize.

This patch cleans up the page reuse code getting it into a state where all
the workarounds needed are in place as well as cleaning up a few minor
oversights such as using __free_pages instead of put_page to drop a locally
allocated page.
It also cleans up how we clear the descriptor status bits. Previously they
were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a
64 bit field and 64 bit writes can be a bit more expensive on on 32 bit
systems. Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared. As a result we can
just clear the status bits and leave the length and VLAN fields as-is which
should provide more information in debugging.

The issue is that test_and_set_bit() done on adapter->state is being
performed *after* the netdevice has been freed via free_netdev().
When netdev is being allocated on initialization time, it allocates
a private area, here struct ixgbe_adapter, that resides after the
net_device structure. In ixgbe_probe(), the device init routine,
we set up the adapter after alloc_etherdev_mq() on the private area
and add a reference for the pci_dev as well via pci_set_drvdata().
Both in the error path of ixgbe_probe(), but also on module unload
when ixgbe_remove() is being called, commit 41c62843eb ("ixgbe:

The patch stores the result in a bool and thus fixes above oops on my
side.

Prior to commit a9b8943ee1 ("ixgbe: remove vlan_filter_disable
