Currently, default VHT configuration from the firmware is used
for the VHT operations. Adding vhtcfg command to configure the
firmware based on input received from cfg.

Enable VHT for AP mode only when cfg80211_ap_settings has a
VHT IE i.e., when ieee80211ac is set to 1 in the hostapd.conf.

Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next

Spin locks and completions are expensive in hard IRQ context and cause
problems with RT kernels.  In RT kernels, both spin locks and
completions can schedule(), so we can't use them in hard irq context.

Move handling code into the irq thread function to avoid that.

Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.

This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.

A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.

When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.

This functionality is STA only currently.
