Well thanks for the pointers to the code and all the other
information. The point is academic as I don't expect that the person
will require enough NICs to seriously encounter any boundary
conditions. Thanks.

I think in practice it breaks down before that. I seem to recall
at work the OS guys were

Today I was asked about the maximum number of NICs supported by the
Linux kernel. My initial response was "probably more than you need".
Its been bothering me that I didn't know where to find the answer. I
looked in include/linux/limits.h, I didn't expect to find it but that
was my first thought.
