Fix undo of reserve() before RX recycle
gfar_new_skb reserve()s space in the SKB to align it. If an error occurs,
and the skb needs to be returned to the RX recycle queue, the current code
attempts to reset head, but did not reset tail. This patch remembers the
alignment amount, and reverses the reserve() when needed.

During FCF solicitation, the switch is supposed to pad the
solicited advertisement out to the endpoints specified
maximum FCoE frame size. That means that we need to receive
FIP frames that are larger than the standard MTU. To make
sure the receive queue is configured correctly, we should be
filtering FIP traffic into the FCoE queues.

Currently FIP (FCoE Initialization Protocol) frames
are going untagged. This causes various problems
with FCFs (switches) that have negotiated a priority
over dcbx. This patch tags FIP frames with the same
priority as the FCoE frames.

If the user buffer count was 256 the shift would place a 1
in the offset region leading to errors. It also overwrites
the uers buffer list. This patch makes sure that at most
256 user buffers are allowed for DDP and the buffer count
is masked properly such that it doesn't overwrite the offset
when shifting the bits.

In the last patch I missed an unecessary min_t comparison.
This patch removes it, the path allocates at most
72 tx queues for 82599 and 24 for 82598 there is no need
for this check.
Additionally this sets MAX_[TX|RX]_QUEUES to 72. Which is
used as the size for the tx/rx_ring arrays. There is no
reason to have more tx_rings/rx_rings then num_tx_queues.

VFs running in guest VMs do not respond in as timely a manner to
PF indication it is going down as they do when running in the host
domain. If the adapter is in SR-IOV mode insert a two second delay
to guarantee that all VFs have had time to respond to the PF reset.
In any case resetting the PF while VFs are active should be
discouraged but if it must be done then there will be a two
second delay to help synchronize resets among the PF and all the
VFs.

and if we receive fragmented packets then the first fragment will be
untracked and thus skip nf_ct_frag6_gather (and conntrack), while all

Add support for basic configuration of a connection quality monitoring to the
nl80211 interface, and basic support for notifying about triggered monitoring
events.
Via this interface a user-space connection manager may configure and receive
pre-warning events of deteriorating WLAN connection quality, and start
preparing for roaming in advance, before the connection is already lost.
An example usage of such a trigger is starting scanning for nearby AP's in
an attempt to find one with better connection quality, and associate to it
before the connection characteristics of the existing connection become too bad
or the association is even lost, leading in a prolonged delay in connectivity.
The interface currently supports only RSSI, but it could be later extended
to include other parameters, such as signal-to-noise ratio, if need for that
arises.
