This patch implements basic WoWLAN support in qtnfmac driver, including
processing of WoWLAN features reported by firmware and implementation
of cfg80211 suspend/resume/wakeup callbacks. Currently the following
WoWLAN triggers are supported: disconnect, magic packet,
custom pattern packet.

Update existing code handling configuration of supported interface
combinations. Current implementation is not complete since it does
not report multiple interface combinations which are incompatible
with each other. Instead current implementation packs all the
supported combinations into single entry.
In fact currently qsr10g wireless card supports the following
two distinct interface combinations:
1. STA/repeater: 1 STA and/or 1 AP
{
{ .max = 1, .types = NL80211_IFTYPE_AP},
{ .max = 1, .types = NL80211_IFTYPE_STA},
}
2. AP/mBSS
{
{ .max = 8, .types = NL80211_IFTYPE_AP},
}
The list of supported configuration is reported by firmware during
wireless card bring-up. Communication protocol between firmware
and host has been updated accordingly in order to accommodate passing
multiple interface combination entries.

an overflow takes place in network packet counters. This patch makes use of

Current recovery approach is to wake s/w Tx queues for skb->dev netdevice.
However this approach doesn't cover the case when h/w queue is full of
packets from a single wireless interface. Suppose xmit attempt from the
second wireless interface fails due to failed reclaim. Then the second
interface will not have a chance to recover even if subsequent reclaims
succeed. Possible solution is to attempt to wake all the s/w queues
belonging to driver interfaces.

This patch adds support for new FullMAC WiFi driver for Quantenna
QSR10G chipsets.
QSR10G (aka Pearl) is Quantenna's 8x8, 160M, 11ac offering.
QSR10G supports 2 simultaneous WMACs - one 5G and one 2G.
5G WMAC supports 160M, 8x8 configuration. FW supports
up to 8 concurrent virtual interfaces on each WMAC.
Patch introduces 2 new drivers:
- qtnfmac.ko for interfacing with kernel wireless core
- qtnfmac_pearl_pcie.ko for interfacing with hardware over PCIe interface
