ff11d8b27d bonding: fix bond_option_mode_set warning
During the conversion to "static" functions this one got left out, only its
prototype was converted, thus resulting in:
drivers/net/bonding//bond_options.c:674:5: warning: symbol
'bond_option_mode_set' was not declared. Should it be static?

Fix it by making it static and also break the line in two as it was too
long.

f54424412b bonding: permit enslaving interfaces without set_mac support
Currently we exit if the slave isn't the first slave, doesn't support mac
address setting and fail_over_mac isn't FOM_ACTIVE. It's wrong because we
only require ndo_set_mac_address in case bonding is in active-backup mode
and FOM isn't FOM_ACTIVE.

To fix this - only exit with an error if we're in a/b mode and have
fail_over_mac != FOM_ACTIVE.

Also, maintain current behaviour on the first slave (forcibly change fom to
FOM_ACTIVE) to not break anyone's configuration.

d762d03849 net: ppp: reset nextseq counter when enabling SC_MULTILINK
If using a demand-dialled PPP unit for a PPP multilink master, the pppd
daemon needs to reset the sequence counter between two connections. This
allows the daemon to reuse the PPP unit instead of destroying and recreating
it. As there is no API to reset the counter, this patch resets the counter
whenever the SC_MULTILINK flag is set.

26c4fdb052 net-timestamp: document deprecated syststamp
The SO_TIMESTAMPING API defines option SOF_TIMESTAMPING_SYS_HW.
This feature is deprecated. It should not be implemented by new
device drivers. Existing drivers do not implement it, either --
with one exception.

Driver developers are encouraged to expose the NIC hw clock as a
PTP HW clock source, instead, and synchronize system time to the
HW source.

The control flag cannot be removed due to being part of the ABI, nor
can the structure scm_timestamping that is returned. Due to the one
legacy driver, the internal datapath and structure are not removed.

This patch only clearly marks the interface as deprecated. Device
drivers should always return a syststamp value of zero.

11878b40ed net-timestamp: SOCK_RAW and PING timestamping
Add SO_TIMESTAMPING to sockets of type PF_INET[6]/SOCK_RAW:

Add the necessary sock_tx_timestamp calls to the datapath for RAW
sockets (ping sockets already had these calls).

Fix the IP output path to pass the timestamp flags on the first
fragment also for these sockets. The existing code relies on
transhdrlen != 0 to indicate a first fragment. For these sockets,
that assumption does not hold.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=77221

Tested SOCK_RAW on IPv4 and IPv6, not PING.

7730b4c7e3 cxgb4/iw_cxgb4: work request logging feature
This commit enhances the iwarp driver to optionally keep a log of rdma
work request timining data for kernel mode QPs.  If iw_cxgb4 module option
c4iw_wr_log is set to non-zero, each work request is tracked and timing
data maintained in a rolling log that is 4096 entries deep by default.
Module option c4iw_wr_log_size_order allows specifing a log2 size to use
instead of the default order of 12 (4096 entries). Both module options
are read-only and must be passed in at module load time to set them. IE:

modprobe iw_cxgb4 c4iw_wr_log=1 c4iw_wr_log_size_order=10

The timing data is viewable via the iw_cxgb4 debugfs file "wr_log".
Writing anything to this file will clear all the timing data.
Data tracked includes:

- The host time when the work request was posted, just before ringing
the doorbell.  The host time when the completion was polled by the
application.  This is also the time the log entry is created.  The delta
of these two times is the amount of time took processing the work request.

- The qid of the EQ used to post the work request.

- The work request opcode.

- The cqe wr_id field.  For sq completions requests this is the swsqe
index.  For recv completions this is the MSN of the ingress SEND.
This value can be used to match log entries from this log with firmware
flowc event entries.

- The sge timestamp value just before ringing the doorbell when
posting,  the sge timestamp value just after polling the completion,
and CQE.timestamp field from the completion itself.  With these three
timestamps we can track the latency from post to poll, and the amount
of time the completion resided in the CQ before being reaped by the
application.  With debug firmware, the sge timestamp is also logged by
firmware in its flowc history so that we can compute the latency from
posting the work request until the firmware sees it.

031cf4769b cxgb4/iw_cxgb4: display TPTE on errors
With ingress WRITE or READ RESPONSE errors, HW provides the offending
stag from the packet.  This patch adds logic to log the parsed TPTE
in this case. cxgb4 now exports a function to read a TPTE entry
from adapter memory.
