1e2a1ebf2a Support short HWRM commands
New Stratus bnxt devices require support for short HWRM commands for VFs
to function.  Enable their use, but only use them if it's both supported
and required... prefer the long HWRM commands when possible.

923e962b98 iflib: Support to padding Ethernet frames to a min size
Some bnxt devices do not correctly send frames smaller than
52 bytes (without CRC), so add a quirk that will pad frames to an
arbitrary size before passing off to the encap routine.

0d88d48b88 bnxt: Add support for new phy_types and speeds - Part #2
Use our ifm_list of supported media types rather than nested switch
statements to find the current media type.  Find a supported type that
matches the current speed.

Remove all workarounds while updating ifmr->ifm_active.

For BNXT_IFMEDIA_ADD, added Three more speeds IFM_10G_T, IFM_2500_T & IFM_2500_KX.

bb993c697a Fix "taskqgroup_attach: setaffinity failed: 3" with iflib drivers
Improved logging added in r323879 exposed an error during
attach. We need the irq, not the rid to work correctly. em uses
shared irqs, so it will use the same irq for TX as RX. bnxt does
not use shared irqs, or TX irqs at all, so there's no need to set
the TX irq affinity.

91577f3772 bnxt: Choose better HW LRO defaults for performance
1) Choose correct Firmware options for HW LRO for best performance
2) Delete TBD and other comments which are not required.
3) Added sysctl interface to enable / disable / modify different factors
   of HW LRO.
4) Disabled HW LRO by default to avoid issues with packet forwarding

This allows much better control over the LRO configuration via sysctls, and
uses much better defaults.  Hardware LRO can now be enabled/disabled
independantly from the software LRO, and the tuning parameters are exposed.

manpage updates coming soon.

- Fix NPAR/VF detection
- Clean up flag definitions
- Don't allow WoL on VFs

Although the bnxt driver doesn't support SR-IOV so can create VFs yet,
the PF could be running Linux or ESCi with a VF passed through to a
FreeBSD guest.  This fixes the driver for that use case.

99c641b97c Roll up iflib commits from github. This pulls in most of the work done
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))"

iflib - reset fl-ifl_fragidx to 0 on iflib_fl_bufs_free().  This caused the

iflib - Handle out of order packet delivery from hardware in support of LRO

Out of order updates to rxd's is fixed in r315217. However, it is not
completely fixed.  While refilling the buffers, iflib is not considering
the out of order descriptors. Hence, it is refilling sequentially.
"idx" variable in _iflib_fl_refill routine is incremented sequentially.
By doing refilling sequentially, it will override the SGEs that
are *IN USE* by other connections.  Fix is to maintain a bitmap of
rx descriptors and differentiate the used one with unused one and
refill only at the unused indices.  This patch also fixes a
few bugs in bnxt, related to the same feature.

d1caaa9300 Clean up MD pollution of bus_dma.h:
--Remove special-case handling of sparc64 bus_dmamap* functions.
  Replace with a more generic mechanism that allows MD busdma
  implementations to generate inline mapping functions by
  defining WANT_INLINE_DMAMAP in <machine/bus_dma.h>.  This
  is currently useful for sparc64, x86, and arm64, which all
  implement non-load dmamap operations as simple wrappers
  around map objects which may be bus- or device-specific.

--Remove NULL-checked bus_dmamap macros.  Implement the
  equivalent NULL checks in the inlined x86 implementation.
  For non-x86 platforms, these checks are a minor pessimization
  as those platforms do not currently allow NULL maps.  NULL
  maps were originally allowed on arm64, which appears to have
  been the motivation behind adding arm[64]-specific barriers
  to bus_dma.h, but that support was removed in r299463.

--Simplify the internal interface used by the bus_dmamap_load*
  variants and move it to bus_dma_internal.h

--Fix some drivers that directly include sys/bus_dma.h
  despite the recommendations of bus_dma(9)
