Add the brcmsmac_tx trace system for tx debugging. Existing code to dump
tx status and descriptors are converted to using tracepoints, allowing
for more efficient collection and post-processing of this data. These
tracepoints are placed to collect data for all tx frames instead of only
on errors. Logging of tx errors is also improved.

Convert most uses of wiphy_* and pr_* for general error and debug
messages to use the internal debug macros instead. Most code used only
for initialization still use wiphy_err(), as well as some locations
which are executed too early to use the debug macros. Some debug

Currently up to 256 frames can be queued for each DMA ring. This is
excessive, and now that we have better flow control we can get by with
less. Experimentation has shown 64 to work well.

nextrxd() is calling txd(), which means that the tx descriptor count is
used to determine when to wrap for determining the next ring buffer
entry. This has worked so far since the driver has been using the same
number of rx and tx descriptors, but it's obviously going to be a
problem if different numbers of descriptors are used.

The brcmsmac internal tx buffering is problematic. The amount of
buffering is excessive (228 packets in addition to the 256 slots in each
DMA ring), and frames may be dropped due to a lack of flow control.
This patch reworks the transmit code path to remove the internal
buffering. Frames are immediately handed off to the DMA support rather
than passing through an intermediate queue. Non-aggregate frames are
queued immediately into the tx rings, and aggregate frames are queued
temporarily in an AMPDU session until ready for transmit.
Transmit flow control is also added to avoid dropping packets when the
tx rings are full. Conceptually this is a separate change, but it's
included in this commit because removing the tx queue without adding
flow control could cause significant problems.

The mac80211 tx queues and brcmsmac DMA fifos both map directly to AC
levels. Therefore it's much more straightforward to queue tx frames and
choose the tx fifo based on the mac80211 queue instead of mapping 802.1D
priority tags to precedence levels then back to AC levels. mac80211
already maps the 802.1D levels to the appropriate AC levels and queues
management frames at the maximum priority, so the results should be
identical.
One functional change resulting from this patch is that AMPDU retries no
longer get a priority boost to queue them ahead of packets with the same
priority already in the tx queue. This behavior will be restored (in
effect at least) in a later patch when the tx queue is removed.

According to the comments this "reduces rate lag," but in reality the
only way this value is used is for determining whether or not any frames
remain to be transmitted. Therefore there's no reason for AMPDU packets
to receive any weighting.

AMPDU session allows MPDUs to be temporarily queued until either a full
AMPDU has been collected or circumstances dictate that transmission
should start with a partial AMPDU. Packets are added to the session by
calling brcms_c_ampdu_add_frame(). brcms_c_ampdu_finalize() should be
called to fix up the tx headers in the first and last packet before
adding the packets to the DMA ring. brmcs_c_sendampdu() is converted to
using AMPDU sessions.
This patch has no real value on it's own, but is needed in preparation
for elimination of the tx packet queue from brcmsmac.

This patch provides extensions to VXLAN for supporting Distributed
Overlay Virtual Ethernet (DOVE) networks. The patch includes:
+ a dove flag per VXLAN device to enable DOVE extensions
+ ARP reduction, whereby a bridge-connected VXLAN tunnel endpoint
answers ARP requests from the local bridge on behalf of
remote DOVE clients
+ route short-circuiting (aka L3 switching). Known destination IP
addresses use the corresponding destination MAC address for
switching rather than going to a (possibly remote) router first.
+ netlink notification messages for forwarding table and L3 switching
misses
Changes since v2
- combined bools into "u32 flags"
- replaced loop with !is_zero_ether_addr()
