The release binding is "minor". Removal of Duplicate BGE/NGE Kstats =================================== We propose to remove the duplicate "mii" and "parameters" kstats from the bge/nge drivers. Details ------- The "mii" kstats duplicate the "mac" MII/GMII kstats that the GLDv3 framework provides for all GLDv3-based Ethernet drivers. When GLDv3 was first integrated, it did not support all MII/GMII kstats, so the existing "mii" kstats in bge/nge were kept. However, PSARC 2007/220 completed the MII/GMII kstats, making it possible to remove the "mii" kstats from bge/nge. Further, the bge/nge drivers also have the "parameter" kstats, which have identical names and semantics as the ndd(1M) parameters. These are redundant and will also be removed. Attempts to retrieve MII/GMII kstats using "kstat -n mii" will fail after this cleanup; "kstat -n mac" should be used instead. Likewise, attempts to retrieve ndd parameters using "kstat -n parameters" will fail after this cleanup; ndd should be used instead. Since only bge/nge and export the two duplicate kstat blocks, while other drivers do not, applications and scripts are extremely unlikely to depend on their existence. Thus, we believe this change is extremely low-risk. Note that the nxge driver has similar issues in that it has "Port Stats" which are mostly duplicated by MII/GMII kstats. But GLDv3 doesn't define 10GB MII kstats yet, so that cleanup will be deferred until GLDv3 is enhanced further.
