Add tools for updating intel network cards firmware

[IAMJDA]

The documentation for the intel ixl driver states additional tools to update the firmware:

   •   To change the behavior of the QSFP+ ports on	 XL710	adapters,  use
   the	Intel  QCU  (QSFP+  configuration  utility);  installed	by the
   sysutils/intel-qcu package.

   •   To update the firmware on an	adapter, use  the  Intel  Non-Volatile
   Memory     (NVM)	Update	   Utility;	installed    by	   the
   sysutils/intel-nvmupdate-10g,   sysutils/intel-nvmupdate-40g,    or
   sysutils/intel-nvmupdate-100g, package.

See https://man.freebsd.org/cgi/man.cgi?query=ixl&sektion=4&format=html

So, it would be great to have sysutils/intel-nvmupdate-10g (I only have slow cards available), but maybe also the rest 😉
