Two months later and still no reaction from Mellanox. They post lots of information here, mainly about new products, but what about taking care of existing products/customers?
I have seen the 2.4.0 drivers published under VPI/VMware driver section, but these are not new drivers, seems like a mistake corrected (these drivers previously appeared under ETH/VMware section). They do add official support for ESXi 6.0, but still no SRP/iSER. So, effectively, they allow using ConnectX-3/Pro VPI adapters as NICs over IB fabric (using IPoIB), but that's it. There seems to be still no support at all(!) for ConnectX-IB and ConnextX-4 VPI adapters, which I find borderline insulting.
Any chance to get ANY reply from Mellanox staff?
