59059cda6a bnxt: Choose better HW LRO defaults for performance
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.

47516844a3 Added support for displaying HW port stats using sysctl.
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.
