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.

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.

- Use HWRM_FUNC_VF_CFG instead of HWRM_FUNC_CFG on VFs
- 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.

This provides port stats (updated once per second) in
dev.bnxt.X.port_stats for PFs. VFs do not have access to the port stats.

1) Based on the suggestion from firmware team, derive
scctx->isc_ntxqsets_max & scctx->isc_nrxqsets_max based on FUNC_QCFG
(instead of FUNC_QCAPS).
2) Bump-up driver version to "1.0.0.2".
