sfc: Use TX push whenever adding descriptors to an empty queue
Whenever we add DMA descriptors to a TX ring and update the ring
pointer, the TX DMA engine must first read the new DMA descriptors and
then start reading packet data. However, all released Solarflare 10G
controllers have a 'TX push' feature that allows us to reduce latency
by writing the first new DMA descriptor along with the pointer update.
This is only useful when the queue is empty. The hardware should
ignore the pushed descriptor if the queue is not empty, but this check
is buggy, so we must do it in software.
In order to tell whether a TX queue is empty, we need to compare the
previous transmission count (write_count) and completion count
(read_count). However, if we do that every time we update the ring
pointer then read_count may ping-pong between the caches of two CPUs
running the transmission and completion paths for the queue.
Therefore, we split the check for an empty queue between the
completion path and the transmission path:
- Add an empty_read_count field representing a point at which the
completion path saw the TX queue as empty.
- Add an old_write_count field for use on the completion path.
- On the completion path, whenever read_count reaches or passes
old_write_count the TX queue may be empty. We then read
write_count, set empty_read_count if read_count == write_count,
and update old_write_count.
- On the transmission path, we read empty_read_count. If it's set, we
compare it with the value of write_count before the current set of
descriptors was added. If they match, the queue really is empty and
we can use TX push.

sfc: Fix event based MCDI completion and MC REBOOT/CMDDONE ordering issue
The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always
sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we
could guarantee to be able to implement this on future hardware.
Given this, I'm less convinced that the protocol should be changed.
To reiterate the failure mode: The driver sees this:
issue command
receive REBOOT event
Was that reboot event sent before the command was issued, or in
response to the command? If the former then there will be a subsequent
CMDDONE event, if the latter, then there will be no CMDDONE event.
Options to resolve this are:
1. REBOOT always completes an outstanding mcdi request, and we set
the credits count to ignore a subsequent CMDDONE event with
mismatching seqno.
2. REBOOT never completes an outstanding mcdi request. If there is
no CMDDONE event then we rely on the mcdi timeout code to complete
the outstanding request, incurring a 10s delay.
I'd argue that (2) is tidier, but that incurring a 10s delay is a little
needless. Let's go with (1).

tcp: Add timewait recycling bits to ipv6 connect code.
This will also improve handling of ipv6 tcp socket request
backlog when syncookies are not enabled. When backlog
becomes very deep, last quarter of backlog is limited to
validated destinations. Previously only ipv4 implemented
this logic, but now ipv6 does too.
Now we are only one step away from enabling timewait
recycling for ipv6, and that step is simply filling in
the implementation of tcp_v6_get_peer() and
tcp_v6_tw_get_peer().

NIC partitioning is another flavor of multi function - having few

and some distinctions between switch dependent (SD) and
