This converts OnAction23a_back23a() to using struct ieee80211_mgmt to
parse the response packet. In addition this revealed a bug which has
been fixed:
case WLAN_ACTION_ADDBA_RESP: /* ADDBA response */
status = get_unaligned_le16(&frame_body[3]);
tid = ((frame_body[5] >> 2) & 0x7);
The above masks the tid to 3 bits, however per ieee80211.h, the tid is
in fact 4 bits wide, as defined by IEEE80211_ADDBA_PARAM_TID_MASK (0x3c)

Use new OF interrupt mapping (of_irq_parse_and_map_pci()) when possible.
This is the recommended method of doing the IRQ mapping. For old
devicetrees we fall back to the previous practice.
This allows interrupts to be remapped across bridges.

In the dst->output() path for ipv4, the code assumes the skb it has to
transmit is attached to an inet socket, specifically via
ip_mc_output() : The sk_mc_loop() test triggers a WARN_ON() when the
provider of the packet is an AF_PACKET socket.
The dst->output() method gets an additional 'struct sock *sk'
parameter. This needs a cascade of changes so that this parameter can
be propagated from vxlan to final consumer.

Sometimes when command timeout occurs due to a firmware or

queue. These commands are never downloaded to firmware causing
hung task warnings. This patch replaces wait_event_interruptible

During extended scan, SCAN report event is always followed by
command response. Sometimes It is observed that command response
is processed before SCAN report which leads to a crash, because
current command node is cleared while handling the response.
This patch makes sure that driver's main thread gives priority
to events over command responses.

commi 30a70b0 (usb: musb: fix obex in g_nokia.ko
causing kernel panic) removed phy_power_on()
and phy_power_off() calls from runtime PM callbacks
but it failed to note that the driver depended
on pm_runtime_get_sync() calls to power up the PHY,
thus leaving some platforms without any means to
have a working PHY.
Fix that by enabling the phy during omap2430_musb_init()
and killing it in omap2430_musb_exit().

ip_queue_xmit() assumes the skb it has to transmit is attached to an
inet socket. Commit 31c70d5956 ("l2tp: keep original skb ownership")
changed l2tp to not change skb ownership and thus broke this assumption.
One fix is to add a new 'struct sock *sk' parameter to ip_queue_xmit(),
so that we do not assume skb->sk points to the socket used by l2tp
tunnel.
