Thanks a ton Sarah.  That was the exactly the right thing to look at. 
For
some reason the "apt full-upgrade" did not install the new version of 
the
linux-modules-extra package, specifically 
linux-modules-extra-4.15.0-64-generic.
Installing that loaded up the complete set of bnx2 modules and support 
for
the Broadcom NIC.
