Currently beacon availability upon association is marked by have_beacon
flag of assoc_data structure that becomes unavailable when association
completes. However beacon availability indication is required also after
association to inform a driver. Currently dtim_period parameter is used
for this purpose. Move have_beacon flag to another structure, persistant
throughout a interface's life cycle. Use suitable sematics for beacon
availability indication.

In multicast, there is no retries nor RTS since there is no

that we must not use the rate scale table for multicast
frames.

In unassociated BSS STA mode FW verifies both power save and power
management flags to decide on switching power off. The driver currently
sets power management flag according to mac80211 decision. As result, in
unassociated mode power management flag is down and power consumption is
high. Change power management enablement. When unassociated in BPS and
LP power save modes enable power management regardless of mac80211
decision. Rely on mac80211 decision if associated. Add power management
state update during associated/disassociated modes transitions.

This corrects an regression introduced by "net: Use 16bits for *_headers
fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In
that case skb->tail will be a pointer whereas skb->transport_header
will be an offset from head. This is corrected by using wrappers that
ensure that comparisons and calculations are always made using pointers.

This patch improves the logic used by the mvneta driver to find a MAC
address for a particular interface. Until now, it was only looking at
the Device Tree, and if no address was found, was falling back to
generating a random MAC address.
This patch adds the intermediate solution of reading the MAC address
from the hardware registers, in case it has been set by the
bootloader. So the order is now:
1) MAC address from the Device Tree
2) MAC address from the hardware registers
3) Random MAC address
This requires moving the MAC address initialization a little bit later
in the ->probe() code, because it now requires the hardware registers
to be remapped.

Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.

In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).
Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

A separate SCD queue is mapped to this fifo - the cab_queue
(cab stands for Content After Beacon). This queue isn't
connected to any station, but rather to the MAC context.
This queue should (and is already) be set as the MCAST

According to the FW implementation, the quota command should
have a valid entry for each active binding (where 'active' in
this context means that the binding is known to the FW). In case
the binding should not get any quota, the 'quota' should be set
to zero.
Not setting an 0 quota for an active binding when all the MACs
in the binding are idle, i.e., not associated in case of managed
interface, will result in preventing the FW scheduler from entering
IDLE state and the FW from transitioning to low PS.
