Rename functions and variables from ixlv to iavf to match the
user-facing name change. There shouldn't be any functional changes
with this change, but this may help with browsing the source code
and reducing diffs in the future.

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.

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.

Refresh upstream driver before impending conversion to iflib.
Major changes:
- Support for descriptor writeback mode (required by ixlv(4) for AVF support)
- Ability to disable firmware LLDP agent by user (PR 221530)
- Fix for TX queue hang when using TSO (PR 221919)
- Separate descriptor ring sizes for TX and RX rings

Uses of mallocarray(9).
The use of mallocarray(9) has rocketed the required swap to build FreeBSD.
This is likely caused by the allocation size attributes which put extra pressure
on the compiler.
Given that most of these checks are superfluous we have to choose better
where to use mallocarray(9). We still have more uses of mallocarray(9) but
hopefully this is enough to bring swap usage to a reasonable level.

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.
