2289559114 Make sure default VNET is set when adding a new interface in mlx5core.
Adding an interface might be done outside the device_attach() routine
and will then cause a panic, due to the VNET not being set.

11546d068d Add timeout handle to commands with callback in mlx5core.
The current implementation does not handle timeout in case of command
with callback request, and this can lead to deadlock if the command
doesn't get firmware response. Add delayed callback timeout work
before posting the command to firmware. In case of real firmware
command completion we will cancel the delayed work. In case of
firmware command timeout the callback timeout handler will be called
and it will simulate firmware completion with timeout error.

Call command completion handler in case of timeout when working in
interrupts mode. Avoid flushing the commands workqueue after acquiring
the semaphores to prevent a potential deadlock.

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.

  2) Prevent new commands from executing and return:

     - 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

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
