1c807f6795 Use the busdma API to allocate all DMA-able memory.
The MLX5 driver has four different types of DMA allocations which are
now allocated using busdma:

1) The 4K firmware DMA-able blocks. One busdma object per 4K allocation.
2) Data for firmware commands use the 4K firmware blocks split into four 1K blocks.
3) The 4K firmware blocks are also used for doorbell pages.
4) The RQ-, SQ- and CQ- DMA rings. One busdma object per allocation.

After this patch the mlx5en driver can be used with DMAR enabled in
the FreeBSD kernel.

30dfc0518a Add support for device surprise removal and other PCI errors.
- When device disappears from PCI indicate error device state and:
  1) Trigger command completion for all pending commands
  2) Prevent new commands from executing and return:
     - success for modify and remove/cleanup commands
     - failure for create/query commands
  3) When reclaiming pages for a device in error state don't ask FW to
     return all given pages, just release the allocated memory

PCI device(s), changes:
- alloc_entry() now clears bit for page slot entry aswell
- update of cmd->ent_arr[] is now under cmd->alloc_lock
- complete command if alloc_entry() fails

66d53750b9 Add support for reading advanced diagnostic counters.
By default reading the diagnostic counters is disabled. The firmware
decides which counters are supported and only those supported show up
in the dev.mce.X.diagnostics sysctl tree.

To enable reading of diagnostic counters set one or more of the
following sysctls to one:

dev.mce.X.conf.diag_general_enable=1
dev.mce.X.conf.diag_pci_enable=1

76a5241f2c Add SR-IOV guest support to the mlx5en driver.
This patch adds the missing pieces needed for device setup using the
mlx5en driver inside a virtual machine which is providing hardware
access through SR-IOV.

fa201e28fc Prepare for activation of LinuxKPI module parameters as read-only
tunable SYSCTL's. Linux module parameters are associated with the
module they belong to. FreeBSD does not share this concept of a parent
module. Instead add macros which define the prefix to use for the
module parameters in the LinuxKPI consumers.

While at it convert all "bool" LinuxKPI module parameters to "byte"
type, because we don't have a "bool" type of SYSCTL in FreeBSD.

98a998d5e7 Update the mlx5 shared driver code to the latest version, which
include the following list of changes:

- Added eswitch ACL table management
  Introduce API for managing ACL table.
  This API include the following features:
  1) vlan filter - for VST/VGT+ support.
  2) spoofcheck.
  3) robust functionality to allow/drop general untagged/tagged traffic.
  4) support for both ingress and egress ACL types.

- Added loopback filter to the vacl table.

- Added multicast list set in the vPort context

- Added promiscuous mode set in the vPort context

- Set the vlan list in vPort context
  1) Check caps if VLAN list is not longer than FW supports
  2) Set MODIFY_NIC_VPORT_CONTEXT command

- Changed MLX5_EEPROM_MAX_BYTES from 48 to 32 so that a single EEPROM
  reading cannot cross the 128-byte boundary. Previously reading the
  MCIA register was done in batches of 48 bytes. The third reading
  would then by-pass the 127th byte, which means that part of the low
  page and part of the high page would be read at the same time, which
  created a bug:
    1st: 0-47 bytes
    2nd: 48-95 bytes
    3rd: 96-143 bytes

dc7e38ac4d Add mlx5 and mlx5en driver(s) for ConnectX-4 and ConnectX-4LX cards
from Mellanox Technologies. The current driver supports ethernet
speeds up to and including 100 GBit/s. Infiniband support will be
done later.

The code added is not compiled by default, which will be done by a
separate commit.
