configures all the supported channels for scanning.
However, this can result in SYSASSERT in some cases,
when the configured channel is disabled.
Instead, configure only the channels given in the

While on it, change the code to use channel->hw_value
instead of recalculating the channel number.

In some cases, we need to force the association to be off in the
MAC_CONTEXT_CMD command we send to the firmware. Instead of having to
hack the vif->bss_conf.assoc value, pass it all the way down the call
chain.
Additionally, for the iwl_mvm_mac_ctxt_add() case, we *always* set
forced_assoc_off to true, so we can remove the hack in the d3 code
that was forcing it to off by hacking the bss_conf.assoc value.

then we will have: read(2K) - return 2K ... read(2K) - return 2K
read(2K) - return the rest (in bytes) and exit the while loop.

A binding object associates virtual MACs to a Phy.
Binding object can ask (and get) air time, thus
allowing several MACs to share the medium.
A binding object can be in either one of 3 states:
1) standalone - A single active MAC
2) Different Channel Mode (DCM) - There are 2 active
MACs or more (not necessarily just clients), but each
has its own channel.
3) Same Channel Mode (SCM) - There are 2 active
MACs or more (not necessarily just clients), that
share the same channel.
This patch introduces an additional condition for enabling uAPSD:
uAPSD should be disabled for a client in DCM.
The reason for that is a low latency issue in Miracast.
