RDMA with QLogic FastLinQ 41xxx and 45xxx (qedentv) on ESXi
So, all the infos I'm giving here can be found in VMware KBs or on the HPE support site, it just took me literal days to find them. My problem was to get RoCEv2 running with the qedentv driver on ESXi, the driver alone doesn't support RDMA. However, the driver comes in a package of 4 drivers or modules where qedrntv does support RDMA. I suspect the "e" in qedentv stands for ethernet and the "r" in qedrntv stands for RDMA? Either way, the solution sounds quite simple, swap out qedentv with qedrntv as the active driver and done. Turns out its not that easy or I wouldn't be writing this...
