Mostly simple overlapping changes.
For example, David Ahern's adjacency list revamp in 'net-next'
conflicted with an adjacency list traversal bug fix in 'net'.

+- vsc8531,vddmac : The vddmac in mV. Allowed values is listed
+ in the first row of Table 1 (below).
+ This property is only used in combination

- the fastest possible edge time. Native sign

+ the fastest possible edge time.
Edge rate sets the drive strength of the MAC
- interface output signals. Changing the drive
- strength will affect the edge rate of the output
- signal. The goal of this setting is to help
- reduce electrical emission (EMI) by being able
- to reprogram drive strength and in effect slow
- down the edge rate if desired. Table 1 shows the
- impact to the edge rate per VDDMAC supply for each
- drive strength setting.

+
+ We plan to remove this option and code, so if you find
+ that you have to enable it, please let us know on the
+ linux-wireless@vger.kernel.org mailing list, so we can
+ help you migrate to 4-addr AP/client (or, if it's really

+ * +---> STARTUP ----+
+ * | | |
+ * | V |

+ * | | | |
+ * | +----+ |
+ * | |
+ * +---- PROBE_RTT <--+
+ *
+ * A BBR flow starts in STARTUP, and ramps up its sending rate quickly.
+ * When it estimates the pipe is full, it enters DRAIN to drain the queue.
+ * In steady state a BBR flow only uses PROBE_BW and PROBE_RTT.
+ * A long-lived BBR flow spends the vast majority of its time remaining
+ * (repeatedly) in PROBE_BW, fully probing and utilizing the pipe's bandwidth
+ * in a fair manner, with a small, bounded queue. *If* a flow has been
+ * continuously sending for the entire min_rtt window, and hasn't seen an RTT
+ * sample that matches or decreases its min_rtt estimate for 10 seconds, then
+ * it briefly enters PROBE_RTT to cut inflight to a minimum value to re-probe
+ * the path's two-way propagation delay (min_rtt). When exiting PROBE_RTT, if
+ * we estimated that we reached the full bw of the pipe then we enter PROBE_BW;
+ * otherwise we enter STARTUP to try to fill the pipe.
