      em(4): Add support for Comet Lake Mobile Platform, update shared code · 51569bd7
      Eric Joyner authored 
      

This change introduces Comet Lake Mobile Platform support in the e1000
driver along with shared code patches described below.

- Cast return value of e1000_ltr2ns() to higher type to avoid overflow
- Remove useless statement of assigning act_offset
- Add initialization of identification LED
- Fix flow control setup after connected standby:
  After connected standby the driver blocks resets during
  "AdapterStart" and skips flow control setup. This change adds
  condition in e1000_setup_link_ich8lan() to always setup flow control
  and to setup physical interface only when there is no need to block
  resets.

      sys/dev: further adoption of SPDX licensing ID tags. · 7282444b
      Pedro F. Giffuni authored 
      Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

      Stephen Hurd authored 
      This was really too big of a commit even if everything worked, but there
are multiple new issues introduced in the one huge commit, so it's not
worth keeping this until it's fixed.

I'll work on splitting this up into logical chunks and introduce them one
at a time over the next week or two.

      Roll up iflib commits from github. This pulls in most of the work done · d300df01
      Stephen Hurd authored 
      by Matt Macy as well as other changes which he has accepted via pull
request to his github repo at https://github.com/mattmacy/networking/

This should bring -CURRENT and the github repo into close enough sync to
allow small feature branches rather than a large chain of interdependant
patches being developed out of tree.  The reset of the synchronization
should be able to be completed on github by splitting the remaining
changes that are not yet ready into short feature branches for later
review as smaller commits.

Here is a summary of changes included in this patch:

1)  More checks when INVARIANTS are enabled for eariler problem
    detection
2)  Group Task Queue cleanups
    - Fix use of duplicate shortdesc for gtaskqueue malloc type.
      Some interfaces such as memguard(9) use the short description to
      identify malloc types, so duplicates should be avoided.
3)  Allow gtaskqueues to use ithreads in addition to taskqueues
    - In some cases, this can improve performance
4)  Better logging when taskqgroup_attach*() fails to set interrupt
    affinity.
5)  Do not start gtaskqueues until they're needed
6)  Have mp_ring enqueue function enter the ABDICATED rather than BUSY
    state.  This moves the TX to the gtaskq and allows processing to
    continue faster as well as make TX batching more likely.
7)  Add an ift_txd_errata function to struct if_txrx.  This allows
    drivers to inspect/modify mbufs before transmission.
8)  Add a new IFLIB_NEED_ZERO_CSUM for drivers to indicate they need
    checksums zeroed for checksum offload to work.  This avoids modifying
    packet data in the TX path when possible.
9)  Use ithreads for iflib I/O instead of taskqueues
10) Clean up ioctl and support async ioctl functions
11) Prefetch two cachlines from each mbuf instead of one up to 128B.  We
    often need to parse packet header info beyond 64B.
12) Fix potential memory corruption due to fence post error in
    bit_nclear() usage.
13) Improved hang detection and handling
14) If the packet is smaller than MTU, disable the TSO flags.
    This avoids extra packet parsing when not needed.
15) Move TCP header parsing inside the IS_TSO?() test.
    This avoids extra packet parsing when not needed.
16) Pass chains of mbufs that are not consumed by lro to if_input()
    rather call if_input() for each mbuf.
17) Re-arrange packet header loads to get as much work as possible done
    before a cache stall.
18) Lock the context when calling IFDI_ATTACH_PRE()/IFDI_ATTACH_POST()/
    IFDI_DETACH();
19) Attempt to distribute RX/TX tasks across cores more sensibly,
    especially when RX and TX share an interrupt.  RX will attempt to
    take the first threads on a core, and TX will attempt to take
    successive threads.
20) Allow iflib_softirq_alloc_generic() to request affinity to the same
    cpus an interrupt has affinity with.  This allows TX queues to
    ensure they are serviced by the socket the device is on.
21) Add new iflib sysctls to net.iflib:
    - timer_int - interval at which to run per-queue timers in ticks
    - force_busdma
22) Add new per-device iflib sysctls to dev.X.Y.iflib
    - rx_budget allows tuning the batch size on the RX path
    - watchdog_events Count of watchdog events seen since load
23) Fix error where netmap_rxq_init() could get called before
    IFDI_INIT()
24) e1000: Fixed version of r323008: post-cold sleep instead of DELAY
    when waiting for firmware
    - After interrupts are enabled, convert all waits to sleeps
    - Eliminates e1000 software/firmware synchronization busy waits after
      startup
25) e1000: Remove special case for budget=1 in em_txrx.c
    - Premature optimization which may actually be incorrect with
      multi-segment packets
26) e1000: Split out TX interrupt rather than share an interrupt for
    RX and TX.
    - Allows better performance by keeping RX and TX paths separate
27) e1000: Separate igb from em code where suitable
    Much easier to understand separate functions and "if (is_igb)" than
    previous tests like "if (reg_icr & (E1000_ICR_RXSEQ | E1000_ICR_LSC))"

      Update the Intel igb driver to version 2.4.0 · 7609433e
      Jack F Vogel authored 
        - This version has support for the new Intel Avoton systems,
including 2.5Gb support, further it now has IPv6/TSO6 support as
well. Shared code has been updated where necessary as well. Thanks
to my new assistant Eric Joyner for doing the transmit path changes
to bring in the IPv6/TSO6 support. Thanks to Gleb for catching the
one bug and change needed in NETMAP.

      Refresh on the shared code for the E1000 drivers. · 6ab6bfe3
      Jack F Vogel authored 
        - bear with me, there are lots of white space changes, I would not
    do them, but I am a mere consumer of this stuff and if these drivers
    are to stay in shape they need to be taken.

em driver changes: support for the new i217/i218 interfaces

igb driver changes:
  - TX mq start has a quick turnaround to the stack
  - Link/media handling improvement
  - When link status changes happen the current flow control state
    will now be displayed.
  - A few white space/style changes.

lem driver changes:
  - the shared code uncovered a bogus write to the RLPML register
    (which does not exist in this hardware) in the vlan code,this
    is removed.

      Part 1 of two parts, this is the shared code changes in · 4dab5c37
      Jack F Vogel authored 
      support of new deltas for both em and igb drivers.

Note that I am not able to track all the bugs fixed in
this code, I am a consumer of it as a component of my
core drivers. It is important to keep the FreeBSD drivers
up to date with it however.

One important note is there is a key fix for 82574 in this
update. Also, there are lots of white space changes, I am
not happy about them but have no control over it :)
