    Setting Global Flowcontrol with ESXi


      How do you disable or enable global flowcontrol in Esxi 6.x with ConnextX-3 adapters?


      VMware has  KB1013413 which states to use one of two methods:


      1.  Ethtool - if the adapter supports it.  I get an error when trying to view or set flowcontrol on Mellanox adaptors  (Can not get control fd: No such file or directory)

                     - I assume that means the mellanox driver doesn't support the ethtool.  The command does work for intel Nics in the same server.


      2.  Use the module parameters.  But here I seem to be missing a global flow control. 

                     - I do have pfcrx and pfxtc options.  Those are disabled but all the docs I read say that those settings do NOT disable flowcontrol globally.


      So how what is the driver option to do this?
