ixl(4): Add FW recovery mode support and other things

Update the iflib version of ixl driver based on the OOT version ixl-1.11.29.

Major changes:

- Extract iflib specific functions from ixl_pf_main.c to ixl_pf_iflib.c
to simplify code sharing between legacy and iflib version of driver

- Add support for most recent FW API version (1.10), which extends FW
LLDP Agent control by user to X722 devices

- Improve handling of device global reset

- Add support for the FW recovery mode

- Use virtchnl function to validate virtual channel messages instead of
using separate checks

- Fix MAC/VLAN filters accounting

ixl/iavf(4): Change ixlv to iavf and update it to use iflib(9)

Finishes the conversion of the 40Gb Intel Ethernet drivers to iflib(9) for
FreeBSD 12.0, and fixes numerous bugs in both ixl(4) and iavf(4).

This commit also re-adds the VF driver to GENERIC since it now compiles and
functions.

The VF driver name was changed from ixlv(4) to iavf(4) because the VF driver is
now intended to be used with future products, not just with Fortville/Fort Park
VFs.

A man page update that documents these drivers is forthcoming in a separate
commit.

ixl(4): Update to use iflib

Update the driver to use iflib in order to bring performance,
maintainability, and (hopefully) stability benefits to the driver.

The driver currently isn't completely ported; features that are missing:

- VF driver (ixlv)
- SR-IOV host support
- RDMA support

The plan is to have these re-added to the driver before the next FreeBSD release.

ixl(4): Update to 1.7.12-k

Refresh upstream driver before impending conversion to iflib.

Major new features:

- Support for Fortville-based 25G adapters
- Support for I2C reads/writes

(To prevent getting or sending corrupt data, you should set
dev.ixl.0.debug.disable_fw_link_management=1 when using I2C
[this will disable link!], then set it to 0 when done. The driver implements
the SIOCGI2C ioctl, so ifconfig -v works for reading I2C data,
but there are read_i2c and write_i2c sysctls under the .debug sysctl tree
[the latter being useful for upper page support in QSFP+]).

- Addition of an iWARP client interface (so the future iWARP driver for
X722 devices can communicate with the base driver).
- Compiling this option in is enabled by default, with "options IXL_IW" in
GENERIC.
