Since r336313, TSO support for LEM-class devices is removed again as it
was before the conversion of {l,}em(4) to iflib(4) in r311849 and as a
result, isc_tx_tso_segments_max is 0 for LEM-class devices now. Thus,
inappropriate watermarks were used for this class.
This is really only a band-aid, though, because so far iflib(9) doesn't
fully take into account that DMA engines can support different maxima
of segments for transfers of TSO and non-TSO packets. For example, the
DESC_RECLAIMABLE macro is based on isc_tx_nsegments while MAX_TX_DESC
used isc_tx_tso_segments_max only. For most in-tree consumers that
doesn't make a difference as the maxima are the same for both kinds of
transfers (that is, apart from the fact that TSO may require up to 2
sentinel descriptors but also not with every MAC supported). However,
isc_tx_nsegments is 8 but isc_tx_tso_segments_max is 85 by default
with ixl(4).
tests for avail > 0, avail can never be 0 within that loop. Thus, move
decrementing avail and budget_left into the loop and before the code which
checks for additional descriptors having become available in case all the
previous ones have been processed but there still is budget left so the
latter code works as expected. [1]

When ABE was added (rS331214) to NewReno and leak fixed (rS333699) , it now has
a destructor (newreno_cb_destroy) for per connection state. Other congestion
controls may allocate and free cc_data on entry and exit, but the field is
never explicitly NULLed if moving back to NewReno which only internally
allocates stateful data (no entry contstructor) resulting in a situation where
newreno_cb_destory might be called on a junk pointer.
- NULL out cc_data in the framework after calling {cc}_cb_destroy
- free(9) checks for NULL so there is no need to perform not NULL checks
before calling free.
- Improve a comment about NewReno in tcp_ccalgounload
This is the result of a debugging session from Jason Wolfe, Jason Eggleston,
and mmacy@ and very helpful insight from lstewart@.

We've got a set of probably damaged hard disks, reporting 0x04,0x02
("Logical unit not ready, initializing command required") in response
to READ CAPACITY(16), where attempts to use START STOP UNIT for recovery
results in 0x44,0x00 ("Internal target failure") after ~1 second delay.
As result of all recovery retries, device open attempt took ~3 seconds
before finally reporting to GEOM that device is opened, but has no media.
If the open was for writing and since it hasn't formally failed, following
close triggered GEOM retaste, opening device few more times with respective
delays.
This change reduces whole time of this cycle from ~12 seconds to ~3 by
giving up on recovery after the first failure.

tftpd(8) should flush a newly written file to disk before ACKing the final DATA

smaller. Hopefully this will fix the intermittent tests in Jenkins.

Use CLSET_TIMEOUT to set the timeout for connections to DSs instead of
specifying a timeout on each RPC. This is done so that SO_SNDTIMEO
is set on the TCP socket as well as specifying a time limit when
waiting for an RPC reply. Useful if the send queue for the TCP
connection has become constipated, due to a failed DS.
The choice of lease_duration / 4 is fairly arbitrary, but seems to work
ok, with a lower bound of 10sec.
For client connections to a DS, set the retry limit to vfs.nfsd.dsretries,
which is 2 by default.
This patch should only affect pNFS connections to DSs.
