I just wanted to download the latest driver for my ESXi hosts from vmware.com.
Then I got a little bit confused, the version numbers of the Emulex driver 'elxnet' are decrementing.
126.96.36.199 Release Date 2016-09-30
12.0.1115.0 Release Date 2018-04-12
188.8.131.524 Release Date 2018-06-08
Which driver should I choose?
Could you provide the complete model name of adapter for which you are looking for drivers.
We are using both Lenovo/IBM branded Emulex OneConnect OCe11100 and Emulex OneConnect OCe14000 in our hosts.
According to the download page the same driver (elxnet) should be applicable to both models:
This Emulex driver enables support for Emulex's OCe11x (DID:0710), OCe14x (DID:0720). Emulex VID:19a2/10df and SVID:10df.
This driver also supports Emulex's equivalent OEM-Branded versions.
What citeria should i use to determin the latest driver? The release date or the version number...
Since I have a similiar issue: check the supported driver version for the specific card!
VMware Compatibility Guide - System Search
In my case (HPE FlexFabric 554M card) I had to use an "older" driver (at least by version number); the latest driver is unstable (and not listed on VMware compatibility page).
If the 12* driver is listed, I would try it (the 11* is maybe a hotfix for an older driver branch).
